Magnetic field lines must always connect to a north magnetic pole and a south pole - field lines cannot be stopped, only redirected around sensitive objects. MRI machines in hospitals are placed in magnetically shielded rooms to prevent magnetic flux from penetrating into other areas. Currently, spacecraft like the Soyuz capsule are limited to orbital flights, however magnetic shielding may make interplanetary flights survivable for the crews of future space vehicles. Magnetic shielding can reroute, but not block, the magnetic field between the two poles of a horseshoe magnet.
Magnetic shielding is a process that limits the coupling of a magnetic field between two locations. Unlike electricity, magnetic fields cannot be blocked or insulated, which makes shielding necessary. Instead of attempting to stop these magnetic field lines, magnetic shielding re-routes them around an object. While the materials used in magnetic shielding must have a high permeability, it is important that they themselves do not develop permanent magnetization. Magnetic shielding is often employed in hospitals, where devices such as magnetic resonance imaging (MRI) equipment generate powerful magnetic flux.
A number of companies will custom build magnetic shields from a diagram for home or commercial applications.
I have issues now in my bandroom with four giant speaker cabs making my macbook pro video jitter. If Mu Metal is used, does it have to touch the face(s) of the pole(s) of the magnet to work? To anon24772: I would suggest the best solution would be to loose the CRT - LCD or Plasma will not be affected and you could end up spending a lot of time and money getting the shielding right. On the Magnetic Shielding page you state that "ionized gas, or plasma" can be used as a magnetic shield. Yeah I probably will to keep it all original and collectible.I was pretty bummed out that the magnet is no good, my bandmate said it was probably dropped, displacing the magnet.
I would agree droppage.Unlikely that EV QTX or Eminence speakers would be expensive in the USA or sound bad.
Seems like with a driver that large, the weight of the cone could create some issues with how the voice coil aligns with the magnet. I could see that the glue possibly melted, super-strong magnet, not worth my time or money.I could buy a replacement basket for like $120 or so after attempting to do this, or I can buy a reckoned Black Widow locally for $130. Mechanisms of origination and social influence of extremely low frequency Eartha€™s electric fields of conservative type and very low frequency spinning electric fields of vortical type are considered in the article. Unlike well-known technical rotating fields, spinning electric fields of natural origination can be considered as a new class of phenomena. Eartha€™s currents, electromagnetic radiation of Van-Allen belts and natural cavity resonators predetermined EMF spectrum in which everything living evolved.
In particular, electrical activity of human brain is related to extremely low frequency (ELF) Schumann waves, extracted by the closed, 40000 km, Earth-ionosphere resonator. On the other hand, same resonator has another, a short-range mode, extracted between Eartha€™s surface and a floor of the ionosphere, 50-80km above.
The profound impact of Eartha€™s magnetic fields on living organisms is fundamentally considered in [1].
Unlike vortical magnetic fields, influence of Eartha€™s conservative electric fields is less studied, partially because of difficulties of overcoming artifacts associated with electric fields produced by an operator (simple grounding the operatora€™s body doesna€™t eliminate the problem completely and isna€™t acceptable sometimes).
However, Eartha€™s own fields can produce even more drastic results than localized industrial fields, because they cover extremely vast areas of human habiting. A simple comparison of Fig.1 and the table above reveals matching the frequency band in the table with the originated ELF spectrum induced by turbulent water.
The comparison underlines the social importance of the problem: natural sources can produce ELF fields which dangerously match in spectrum that of human organisms while being more powerful. Naturally-originated alternating electric charges cover vast areas, producing great integrative contribution in originated alternating field in every point.
The conservative Eartha€™s fields can induce such the under-crania electric potentials, which drastically exceed that of the brain. Parametric oscillations manifest themselves through so-called secondary sources: surface electric charges, which origin on a border between two medias in a primary field of some source. For the Nature, electrophysical properties of the media can be shown as a complex dielectric permittivityi??.A  Generally, i??. Considering a social aspect of this type of oscillations, we have to note that existence of pathogenic zones is related to presence of subterranean waters.
Another example: a flow of subterranean water comprises the bubbles, which collapse pretty frequently, generating even higher frequencies, which correspond to theta waves, 4-8 Hz, associated with drowsiness, hypnosis, lucid dreaming and light sleep.
Virtually, each disease has its own EEG-pattern, which sometimes is seen on EEG-record even before the clinical symptoms appear [9].
VLF-action of the Natural EMF is related to phenomenon of a spinning electric vector, SEV [6-8]. The SEV is formed by superposition of two AC fields, extracted by a natural resonator within VLF band, and then gained a phase shift j. A A  Fig.1 shows the resonant VLF-band at 6kHz, a whata€™s more, the frequency of its maximum can vary depending on condition of the ionosphere. SEV is a material object, having angular momentum, and, therefore, it can be defined as a virtual gyroscope [8].
N.A Kozyrev, prominent Soviet astrophysicist (1908-1983), has shown gravity reduction effects in his experiments with mechanical gyroscopes, which was confirmed by other researchers.
The author has developed special means to study both Eartha€™s and industrial EMF fields [10]. For studying spinning fields, SEV, another instrument was developed: Spinning Electric Vector Analyzer, SEVA. The experiments with both the instruments revealed both industrial fields and Eartha€™s fields.
The experiments with ELF-meter revealed strong correlation between weather and ELF-portion of the spectrum: impending clouds, their electric charges, drive heavy activity in this portion of the spectrum, as much as 10 times. Scanning country landscape with ELF-instrument also revealed some spots of the elevated subterranean activity as possible indicators of turbulent water streams. Special experiments were conducted with the motion conversion: the ELF-meter in the moving car registered electric-pulse activity as the car was driven along the road with regular planted trees aside. Also, the meter displays heavy ELF-activity around moving human being and especially inside an active crowd. The considered above conservative ELF and vortical VLF fields are related to a social factor. Unlike ELF electric fields, action of natural VLF spinning fields is based on more subtle mechanism of space-time distortions. For the Nature, electrophysical properties of the media can be shown as a complex dielectric permittivity .A  Generally, . If you look out your window but cana€™t see the masts because they are obstructed by other buildings then the power density will be mainly absorbed by those buildings and too low to worry about. If the substation is immediately next to your home there is little in a practical sense you can do to reduce the magnetic fields. Unless the substation is immediately adjacent to your house the EMFa€™s from these small street substations fall to background levels within about 3 meters. WI-FI and DECT phones are overwhelmingly the main contributors to household electro pollution with power densities far above any nearby mobile phone mast. If your internet connection is by telephone you will need the Netgear DG834 model opposite. If your internet connection is via a cable connection you would need the Linksys wired modem opposite. These alarms use the same technology as DECT cordless phones and will continuously pulsate microwave energy throughout the babya€™s room and beyond.
Best to change your old cathode-ray monitors (the ones with the deep backs) to any type of flat screen monitor as these give of far less Electromagnetic fields than the old type which thankfully you cana€™t buy any more. In order to get your body back to its proper earth bound resonance you need to be sleeping earthed.A  Explanation of what is sleeping earthed and how you can do it is found on my website.
Geobiology explores the relationship between life and the Eartha€™s physical and chemical environment. The history of geobiology in this respect dates back to 1929 when a German aristocrat Baron Gustov Von Pohl, an eminent dowser, made the extraordinary claim that cancer was caused by a€?energy linesa€™ that ran under the beds of the people that had died from the disease. Underground Streams: a€?Water will flow through any underground passage, fracture of fissure.
The dark square with flashing white lines is a photographic print of microwaves radiating in the space above an underground watercourse taken in total darkness. Diagram depicts the flow of underground water and consequential chemical reactions within certain geological features that could be the origin of geopathic stress issues. The dipolar nature of water molecules can also be part of the origin of electromagnetic fields originating from ground contained water. The electromagnetic spectrum refers to the range of different types of Electromagnetic Radiation.a€?These are usually sorted by the frequency. For visual explanation, NASA have a simple but useful diagram, and there is a far more detailed diagram available from thinkgeek (purchase required). We believe that one of the main reasons that EMFs (particularly microwave frequencies) are potentially bioactive is due to the nature of the signal itself. We have evolved with the natural levels of EMFs produced by both the sun and world around us. Power frequency (50Hz in the UK) is given off by any appliance or transmission of AC (alternating current) electrity. Childhood leukaemia has been internationally accepted as linked to powerfrequency exposure magnetic fields, with a wealth of literature finding increases in risk to this and other illnesses. It is well documented and generally accepted that over-exposure to ultraviolet rays can cause burning and skin cancer. There are internationally accepted guidelines by the International Commission for Non-Ionising Radiation Protection (ICNIRP) that have been designed to limit both residential and occupational exposure to levels that are safely below those that can heat up tissue.
However, recently there has been a number of studies showing very specific biological effects far lower than these levels (see our Studies list), and as yet there is no international guidance that has taken any of these studies into effect. Powerfrequency electromagnetic fields are generated by any appliance running off AC (alternating current) power - anything plugged into a main power socket will generate them to some degree.
At the moment, health effects primarily associated with powerfrequency EMFs are due to the magnetic component - these include, but are not limited to, Childhood Leukaemia, Adult Leukaemia, Amyotrophic Lateral Sclerosis, Miscarriage, and Clinical Depression.
There is a fairly brief overview of health risks and evidence in the health concerns section of the electric power transmission article on Wikipedia. The last type of geopathic disturbance that I want to talk about before we have a look at man-made electromagnetic energies concerns the earth's natural geomagnetic field (the one that makes a compass needles pointA  north).
The first geomagnetogram (G1) typically represents the values of the Earths normal geomagnetic field taken by me in a farmer's field near Poynings village not far from where I live. The second geomagnetogram (G2) was taken above a sprung mattress from a lady suffering from chronic fatigue syndrome and severe depression, and has a magnetic anomaly of 22,435.4 nT.
The Cliff of Tears a€?It is important not to underestimate the value of the earth's natural geomagnetic field (DC Field) which interacts with our bodies in many positive waysA  This DC field rarely shows an anomaly above or below 2% of its normal strength which differs according to the latitude in which you live. Unnatural Alterations in the Earth's Geomagnetic Field a€?A second and equally important influence on the sequence of mitosis is the role in which the normal earth's geomagnetic field (DC field) influences the formation and production of a healthy pregnancy. Health risks due to exposure to electromagnetic fields EMFa€™s in the home were first suggested in America by Wertheimer and Leeper, when they estimated the levels people were exposed to, using a€?wire codesa€™, and the local incidence of childhood leukaemia.
Stress sensitive hormones such as prolactin and thyroxide have been found to be elevated in people at work in high electromagnetic environments.A  Prolactin plays a key role in moderating parts of the neuro-immune system and may also be an important precipitator of auto immune diseases. It has been scientifically proven for the first time, with a double blind study by means of an electrocardiogram, that the detrimental effects of a€?water veinsa€? and other geopathically disturbing phenomena can cause serious health problems to persons exposed to them. This presentation took place in March 2003 in the large auditorium of the Saint Johanns-hospital Landesklinjken SalzburgA  Germany. At locations where Geopathic stress zones are present, subsurface water plays a predominantrole, either as lakes, slowly moving underground water, or as water streams. Technical electromagnetic fields can also drastically affect the human body, as soon as certain field strengths are reached. The electromagnetic spectrum refers to the range of different types of Electromagnetic Radiation.These are usually sorted by the frequency.

Packaging should be the same as what is found in a retail store, unless the item is handmade or was packaged by the manufacturer in non-retail packaging, such as an unprinted box or plastic bag. Import charges previously quoted are subject to change if you increase you maximum bid amount. When these "blow" they should be replaced with the same (Ampere) rating as the original (faulty) fuse.
Shielded rooms are constructed to prevent this equipment from interfering with surrounding instruments or meters. Shielding using superconducting magnets is being researched as a means of shielding spacecraft from cosmic radiation. There is a product called pedalsnake, which basically moves all your power supplies (for pedalboards with lots of power supplies) away from the pedals and placed behind the amp. If a 'gap' is allowed between the face of the Mu Metal and the face(s) of the magnet, will that reduce its effectiveness? I have been doing this project at school and was at a loss the whole of today searching for sites, where the explanations were not post-graduate science!!!!
Let's say a person has a small, narrow room in which a CRT TV is being used, and the only location for two big speakers is on either side of the TV. Would recommend adding a replaceable baffle on the back of the box which one could bolt different tuning ports into to experiment with box tuning, have found that what box tuning one wants depends upon what music one is playing, and would allow the cabinet to be used with the rear baffle (ported or transmission line) removed to allow open-backed operation, fig-8 mode.Would also be pretty interesting to do an 18 inch cabinet with a bunch of passive radiators on the back.
That cabinet probably stands 8ft tall and is all speaker, that won't have the usual problems of not coupling to the air at low frequencies and not having enough area.One of these (in working condition) recently sold on Craigslist for $550. But if you are, go for it, I guess.In the search for more bass, bigger speakers is the way to go. I'm not sure what happened there, but the coil was wedged in and I had to pull it out with pliers.
Just bolted the stand through the polepiece vent, sit the snare where you want it, then zip-tie the basket legs through the lugs.


Ita€™s shown that the first category (conservative fields) of natural fields overlaps the spectrum of own frequencies of human organism and can disturb pace of organism. It supports very low frequencies, VLF, 3-30kHz.A  Quantitative difference between both modes brings to their different qualitative action on mankind. The blue lower line shows the original not-disturbed spectrum, while the bright upper line is a result of influence of turbulent water. In particular, the spectrum of Eartha€™s fields overlaps that of electroencephalography (EEG).
Its action is based on originating a vortical electric field, which has low amplitude at such the low frequencies.
Beside that, the motion forms an alternating magnetic field, which, however, can be ignored at relatively low speeds of our everyday life.A  Physiological action of the formed electric fields considerably depends on speed. The instrument comprises a quadrupole sensor with two pairs of mutually orthogonal plates, connected to two parallel channels of band-pass filters having VLF center frequency. This can explain change for the worse of human physiological sensation during changing weather: brain and other organs waves entrainment takes place.
The motion converted patterns of electric fields around the trees into periodic pulsed of theta-wave spectrum, as was discussed above. In cities, harmonics of industrial frequency furnish conditions for developing spinning fields. It has to be said, that this activity depends on a season, time of a day, weather and other factors.
Fig.3 shows an oscilloscope image of SEV originated at the corner of the metal box in a room.
Field rotation possesses gyroscopic properties, which in-turn, can influence space-time reality, as this showed N.A.
Or if you are addicted to cordless phones by the low energy Eco + friendly types that only emit a signal when you are using them.A  Google Siemens Gigaset Low Radiation Phones. An example of this is a digital bedside alarm clock that only need 6 volts to operate but plugged into your 240 volt ring circuit.

The term was adopted many years ago by some German dowsers, a€?geobiologistsa€™ who specialised in surveying houses for both geopathic and electromagnetic stress using both dowsing and scientific instruments. To test his theory he persuaded the Mayor of the Bavarian town of Vilsbiburg to allow him to survey the town for such energies with his dowsing rod. As it does so it produces its own electromagnetic field often high into microwave frequency. It has been known for a long time that when there is flowing water under a dwelling the inhabitants always feel more tired, are prone to premature aging and have a loss of vitality than those who sleep above neutral ground.
As an extremely dialectic medium, water favours the formation of potential vortices, which immediately after their formation contract swiftly. Background levels of EMFs vary hugely depending on which part of the spectrum being looked for - natural light is an obvious example.
Electrical wiring creates electric and magnetic powerfrequency fields throughout houses and other wired buildings, but these levels are usually very low unless there is a wiring fault.
Most areas of science can only deal in probabilities, and that becomes clearer as more scientific studies investigating health effects are produced. There is more disagreement about ill health effects from radiofrequency radiation, which is newer for most of the population, though a well-established 'microwave sickness' has been described.
As a result fortunes are spent on protective sun cream and information services as to prudent avoidance of such exposures. Molecules in the food are vibrated by high levels of microwave frequency Electromagnetic energy, causing it to heat up and subsequently cook.
This, coupled with misleading statements designed to imply that there is currently no published evidence showing a link from organisations such as WHO, are the primary reasons why this topic remains in such hotly-disputed contention.
ICNIRP have set guidelines for residential and occupational exposure to powerfrequency magnetic fields, based primarily on electric shock responses and induced currents, currently set at 100 microtesla (AµT) - equivalent to 1 Gauss.
The evidence on these is mixed, but the link with Childhood Leukaemia is now considered to be pretty solid, with a doubling in risk at magnetic fields above 0.4 AµT (again far below the guidelines set by ICNIRP).
The bottom line is that nature neverA  intended us to sleep on such a disturbed site as shown in figure G2 which has been artificially produced by the bed being placed near to a radiator ( causing the high spike to the right of the graph)A  and the springs causing the rest of the disturbed site.
As you can see the magnetic contours of this bed size area (6a€™x4a€™) are very gentle and slightly undulating showing an overall geomagnetic anomaly of 582 nT (nano Tesla). The sprung mattresses I have measured so far over the past two years have had magnetic anomalies between 4,000 and 61,000 nT. However there are instances in nature where abnormal magnetic anomalies exist usually due to a sudden change in mineralogy or geological structure over a short distance. It appears that the exposure of a dividing cell to an inhomogeneous DC magnetic field causes a physical force to be exerted on the chromosomes or on one of the other microscopic structures associated with mitosis, resulting in structural abnormalities in the chromosomes.
Since that time, international research has increased year by year, and the potential health risks have been identified as cancer (especially childhood leukaemia, probably the most studied illness because of the original findings), depression, suicide, miscarriage, some forms of dementia, respiratory and immune system problems. Research by scientists such as Ross Adey in the USA and Dr Cyril Smith here in Britain is moving the frontier of our understanding.
Hubank of Vienna: a€?Speaking at a conference in England paid tribute to a group of Austrian researches composed of medical doctors, physicists and biochemists. There is clear indication that a combination of technical fields and Geopathic stress zones can multiply the effect and therefore become extremely harmful to all living beings. If you reside in an EU member state besides UK, import VAT on this purchase is not recoverable. Similar rooms are used in electron beam exposure rooms where semiconductors are made, or in research facilities using magnetic flux. This made a huge difference in noise reduction associated with having the power so close to the pedals! At that size, I wonder if the traditional method of a coil in a magnet is the best way to move a cone. Where there are no replacements, enthusiasts strip down and rebuild where others simply can't be bothered. The originated field, in turn, causes passing electric current (so called eddy current) through the cells, disturbing their normal functioning.
Indeed, a brain is a heterogeneous structure, where conductive areas alternate with non-conductive gaps. Shpilaman cause heavy SEV, and what is more, there is a spinning electric process remaining for hours after turning off the axion generators. The next stages of the instrument measure a phase shift between the signal at output of the channels, their amplitude and then calculate spinning S. The sporadic character of the train of pulses matches turbulent flowing subterranean water. The experiments with the digital spectrum analyzer, Fig.1, have revealed seasonable variation of the VLF 6kHz ionosphere resonance, which partially explains these facts.
Spinning Electric Field As a Virtual Gyroscope: On Possibility of Existence of Kozyreva€™s Effect in Spinning Fields. The Mayor agreed and in January that year Baron Von Pohl accompanied by the Mayor and other officials measured numerous energy lines that ran through the streets and houses of the town. This field will fluctuate depending on what is dissolved in it, how fast it is flowing or whether it is interacting with any other type of earth energy. While water running beneath a domestic dwelling should be avoided, a stream situated nearby and open to the sky will favourably discharge its negative energies harmlessly into the atmosphere. Taking its electric charge distribution in to account, turning a water molecule will result in a changed field composition.
The electric field is produced by stationary charges, and the magnetic field by moving charges (currents).
The earth's magnetic fields are static fields, unlike man-made alternating current (AC), which has no natural counterpart.
Unfortunately the studies are not always well done, and the flaws in any given study (showing an effect or otherwise) are often not reported. Precautionary levels which will protect us from illness have not been agreed on, as some countries wish the levels to be lower than others. If you stood in front of an operational microwave with no door your insides would slowly be cooked. The reason for these abnormally high magnetic abnormalities is a result of the bed springs intensifying the magnetic flux of these fields, made worse by the interaction of high magnetic fields around the bed and house from numerous electrical appliances, extension cables running under the bed and transformers placed near to the bed.
One instance of this is in the USA, at a place called Gyngywamp, near Croton, Connecticut knownA  as 'The Cliff of Tears' where visitors to this site very frequently become depressed, gums start to bleed and nose bleeds occur.
Messages pass between the brain, nerves and organs and even from cell to cell by electro- magnetic signalling. In the course of several years research using classical medical methods they investigated about 1000 people for the effects of these geopathic interference zones. There were about 400 people present including numerous renowned specialists; physicians, physicists and geologists, in the all-German audience.
Also, metal ions moved by water can induce small intensity broadband electromagnetic fields (EMF).
58a61a8576Also one could design a rear panel which works as a riser stand, putting a bass reflex port under the open backed cabinet folded underneath to face forwards under the speaker. If one could nick the speaker and design the box out of fiberglass foam core, then it might become portable enough for two people to lift, one would hope most of that 1.5 weight was plywood. But, as explained, as a general rule, you'll be able to get much more bottom out of it than a single smaller driver.
Therefore, a local field in the physiological gaps can drastically exceed the external electric field. Geo-faults, natural heterogeneities, corners and other factors can stimulate origination of SEV. Fig.1, representing the experimental data of the author, shows obvious 6 kHz- resonance in Eartha€™s cavity resonator formed by Eartha€™s surface and floor of ionosphere. The axion field-SEV-relation experiments, conducted by the author in November 2006 revealed the phenomenon of remaining rotation of SEV after switching off the axion generator. Sources Of Bio-Active Radiation Collection (in Russian), Moscow Science-and-Engineering Association Of Radio Engineering, Electronics and Communication, 2006, pp.9-25. Baron Von Pohla€™s energy lines were then compared with the towna€™s record of houses where people had died from cancer during the last ten years, which showed a remarkable coincidence. Dr WA?rst conducted experiments in several German towns, in the rooms of cancer patients and found unusual amounts of gamma radiation in the houses he surveyed using a Geiger a€“counter.
Interference with the earths natural energy field is particularly marked by the flow of these underground streams especially where two watercourses or other types of energy line cross. If thus in a pipe a hydronamic flow vortex is produced, an electric and magnetic vortex and eddy current, are the result. Microwave frequency exposure is a relatively new phenomenon: 100 years ago the background radiation was millions of times lower than it is now, and it is as recent as the mobile phone boom (~1990's) that the modern, digitally pulsed signals have become ubiquitous in the Western world. Because of this, microwave ovens are stringently designed against leaks, and opening the door operates a safety mechanism which disables the oven, thus removing the risk to the operator.
Within our evolutionary history our bodies own magnetic field has integrated with this magnetic field which is responsible for controlling amongst other things, circadian rhythms, mood changes and certain hormone production such as melatonin and serotonin. Our forefathers sleeping on straw or feathered mattresses in houses devoid of any electrical fields or microwave energy would not have experienced such geomagnetic disturbances.
Much of the research in the past 35 years into EMF health effects has concentrated on magnetic fields because they are easier to measure and it was thought they were more likely to interact with our bodiesa€™ cells.
When this is interfered with by outside EMFa€™s problems begin to emerge, as the systems that control and regulate our bodies are impaired. They found that the altered electrical and magnetic field above a geographical distressed zone changed the electrical impulses passing along the nerves of the body. But even in an oven with natural convection, it can mess up airflow and cooking and even cause burners to malfunction. Is there any material I can purchase to cover or wrap the supplies to manage the electromagnetic interference? Inertia would be working against you for higher frequencies, but from subsonic up to 50-60Hz, it might work. Problem with making panels bigger is that you need to make them much thicker to be stiff, this is a visible problem with oldschool scoops with 8ft spans made by rastas out of too-thin cheap plywood, they rip themselves apart and vomit splinters, you can see the horn visibly flexing and forming standing waves along its surface, with all the corners ripping themselves free from the wood and buzzing. Inertia would be working against you for higher frequencies, but from subsonic up to 50-60Hz, it might work.You're halfway right about linear actuators, but the problem with the standard linear actuator is that it's a rotary stepper or DC servomotor attached to a threaded rod.
0Plans.pdfI would ABSOLUTELY LOVE to build one if these for somebody if they do turn up an EVM 18B.
To study this phenomenon, spinning electric vector analyzer, SEVA, was developed by the author. Therefore, big groups of people can be exposed to brain waves entrainment factors, which can influence their health and social behavior. Well this surprised the establishment at the time, and knowing Vilsbiburg to have a high degree on cancer victims anywayA  he was asked to repeat the exercise in the City of Stetten which had a far lower incidence of cancer thus ironing out any chance factors. StA¤ngle, who had a very good reputation of locating water bearing fissures in crystalline rock with his dowsing rod developed a stintilisation counter more sensitive and accurate than a Geiger counter and carried out a scientific survey in the French town of Moulins where a local physician, Dr, J Prichard claimed that cancer victims in the town dwelt above geological faults. In a league table of radiation associated with biological damage, the outside line of a subterranean water course would be at the very top since it is found in association with many terminal and debilitating diseases. You can't see, feel or hear electromagnetic fields, apart from visible light, which is a part of the electromagnetic spectrum. Each static magnetic field bump or sink on geomagnetogram (G2) may speed up or slow down body fluids (blood and lymphatic) in exposed areas such as the brain, heart, lung, liver, legs etc. Most scientists believe that, although EMFa€™s do not directly cause the illness in most cases, at least, living in fields above 200 nT (nano Tesla) may make a person develop the cancer or other illness, when if they didn't live in this field level, their bodies would be able to repair themselves, or cope with the daily damage from other causes in a healthier way. This wrong or confused information resulted in the dysfunction of individual organs and also explained the high number of diseases. If you simply must line the bottom of your oven with foil, at least poke holes in it where there are holes in the oven floor. A proper bass speaker generates some pretty serious air pressure, which can and does blow cabs apart in my experience, once a seam starts to go the whole cabinet can start to disassemble itself violently and chip away the laminates of plywood quite vigorously, given meaty enough amps and large powerful speakers, which can also get hot enough to fry an egg on or burn your skin to fine ash if you touch them, one of the reasons why the dub sound systems like to mount the speakers inside-out, magnet assembly facing out of the box. Whilst WA?rst and StA¤ngle thought that gamma radiation from fissures could be a significant cause of cancer, more recent studies suggest that this is unlikely as gamma radiation tends to whiz straight through the body rather than causing direct hits on DNA. Sleep time exposure to the same sharp variations of magnetic fields for years may induce some chronic health effect.
Indeed, in the town nearby, doctors and nurses are familiar with this sudden onset of illness in visitors to this old Indian sacred site. They proved a weakening in the immune system, which interacts with the wrongly programmed nervous system in persons who had been exposed. Using a randomized double blinded trial*, it has been scientifically shown that Geopathic stress zones do cause chronic stress and therefore can weaken the body's defence systems. Finally, this stress, in combination with a possible suppression of certain functions of the immune system. They're there for a reason.2-1 BASIC REPAIR AND SAFETY PRECAUTIONS1) When working on gas cooking equipment, if you've disconnected a gas pipe to replace a valve or other component, always test the pipe joint for leaks when you reassemble it. Harger, chairman of the city's medical scientific association, declared that all such a€?deadly earth currentsa€™ ran beneath the beds of all the 5,348 people who had died from cancer during the last 21 years. The culprit is thought to be the more pernicious alpha radiation from Radon which is found with high levels of gamma radiation.


The World Health Organization in a health criteria report recognizes interactions between variations in static magnetic fields in cellular tissues to include an induction of electrical potentials and magneto hydrodynamic effects in the circulatory systems and by direct stimulation of nerve and muscle cells even under extremely weak thresholds.
The causation seems to be that within a few meters the geomagnetic DC field varies from 330 milligauss at an 80 degree dip to 700 milligauss at a 59 degree dip. Confirmation of these experiments continue to appear and links have been, formed with the onset of cancer, Alzheimer's Disease, Chronic Fatigue Syndrome, Miscarriages, Multiple Sclerosis (MS) and other diseases of the central nervous system. You can do this by coating the joint with a solution of liquid soap and water and looking for bubbles. Research in this field continues with an increasing number of sophisticated environmental measuring instruments coming on the market to aid the geobiologist in identifying causative factors to illness and disease. The very high electric fields associated with high voltage overhead power lines also cause air ionization, charging toxic aerosols so that they become even more dangerous. Apply it with a brush to make sure you coat the joint thoroughly, and use a mirror to look at the back side of the joint if necessary. To varying degrees the health consequences of staying above one of these geopathically stressed locations can be replicatedA  in our own homes by the choice of mattresses we use.A  The bottom line is, if you suspect your sleeping site is being disturbed by an unusually high magnetic anomaly then buy a bed that has a wooden base and place there upon a mattress that has no springs and make sure it is not placed near a radiator or other heavy metal object. In the 1930a€™s a French engineer Pierie Cody who lived in the sea-port of Le HavreA knew of local a€?cancer housesa€™ in the port where many people had died from cancer over the years. Your appliance parts dealer has gas leak testing solution, with a brush built into the cap, made specifically for this purpose. 2) Always de-energize (pull the plug or trip the breaker on) any oven that you're disassembling.
This equipment known as the Genitron Felix - 3 detects ultra short and radio microwave frequencies with the ability to print them out on a [UKW- Spektrometer und Linienschreiber] This equipment is used in German universities and research institutes that confirms dowsable energy above subterranean water lines. Effects central nervous system and the brain in the ways which effect powerful hormonal mechanisms.
If you need to re-energize the oven to perform a test, make sure any bare wires or terminals are taped or insulated. It's perfectly possible to take a flat sheet of anything and roll it into a cone like a very flat party hat, then truncate the cone, glue on the voicecoil former and suspension, and that's a speaker. After checking large numbers of these dwellings, Cody concluded that the air in these a€?Cancer Housesa€™ were ionized to an unusual degree.
Important areas to be aware of are bedrooms, especially where pillows are on beds, because EMFa€™s affect an area of the brain, called the pineal gland, which works to protect the body against illness overnight. Energize the unit only long enough to perform whatever test you're performing, then disconnect the power again. 3) If this manual advocates replacing the part, REPLACE IT!! From various other tests Cody concluded that the ionization radiation consisted of positively charged Alpha Particles. It is also a good idea to look at places like a favourite armchair, or in front of a computer or TV. The only known source of alpha particle emission in dwellings was from a radioactive gas called Radon. It is important that places like these where you are sitting or lying still for a longish period of time should have low EMFa€™s; cells tend to cope better with external fields if the person is moving around.
When you are sitting still and particular cells keep being interfered with by EMFa€™s, there is an increased risk that the damage may become unrepairable.
There is a reason that it stopped - you can bet on it - and if you get it going and re-install it, you are running a very high risk that it will fail again. It is worthwhile taking particular precautionary action with regard to childrena€™s living environments. Replace the part. 4) Always replace the green (ground) leads when you remove an electrical component. Wear gloves, and be careful not to cut your hands! 6) If you have diagnosed a certain part to be bad, but you cannot figure out how to remove it, sometimes it helps to get the new part and examine it for mounting holes or other clues as to how it may be mounted. 7) When testing for a 110 volt power supply from a wall outlet, you can plug in a small appliance such as a shaver or blow dryer.
If you're testing for 220 volt power you need to use the VOM. 8) When splicing wires in an oven, remember that you're dealing with high temperatures. Your parts dealer has high-temp connections, porcelain wire nuts and fiberglass-insulated wire for this purpose. I want to impress upon you something really important. It's unpleasant, but unless exposure is more than a second or so, the only harm it usually does is to tick you off pretty good. However, you don't want to badger them with too many questions, so know your basics before you start asking questions. Some parts houses may offer service, too. They'll tell you it's too complicated, then in the same breath "guide" you to their service department. If they genuinely try to help you fix it yourself, and you find that you're unable to, they may be the best place to look for service.
On some models, you will also need the lot number to get the right part, so if there is one on the nameplate, write that down, too.2-3 TOOLS (Figure 2-A)Most of the tools that you might need are shown below.
An inexpensive one will suffice, as long as it has both "AC Voltage" and "Resistance" (i.e. It's true that diagnosing and repairing electrical circuits requires a bit more care than most operations, due to the danger of getting shocked. Remember the rule in section 2-1; while you are working on a circuit, energize the circuit only long enough to perform whatever test you're performing, then take the power back off it to perform the repair. You will only need to be able to set the VOM onto the right scale, touch the test leads to the right place and read the meter.In using the VOM (Volt-Ohm Meter) for our purposes, the two test leads are always plugged into the "+" and "-" holes on the VOM. It's derived from the word "continuous." In an electrical circuit, electricity has to flow from a power source back to that power source.
It should peg the meter all the way on the right side of the scale, towards "0" on the meter's "resistance" or "ohms" scale. If the meter does not read zero ohms, adjust the thumbwheel on the front of the VOM until it does read zero.
If the ignitor's leads are still connected to something, you may get a reading through that something. You can touch the ends of the wires and test leads with your hands if necessary to get better contact. If there is GOOD continuity, the meter will move toward the right side of the scale and steady on a reading. This is the resistance reading and it doesn't concern us; we only care that we show good continuity. If you do not, the switch is bad. 2-4(c) AMMETERSAmmeters are a little bit more complex to explain without going into a lot of electrical theory. If you own an ammeter, you probably already know how to use it. If you don't, don't get one. To determine continuity, for our purposes, we can simply isolate the component that we're testing (so we do not accidentally measure the current going through any other components) and see if there's any current flow. To use your ammeter, first make sure that it's on an appropriate scale (0 to 10 or 20 amps will do). If the meter shows any reading at all, something in the oven is using power.2-5 WIRING DIAGRAMSometimes you need to read a wiring diagram, to make sure you are not forgetting to check something.
The symbols used to represent each component are pretty universal. Wire colors are abbreviated and shown next to each wire.
GR or GN are green, GY is gray.A wire color with a dash or a slash means --- with a --- stripe. In some wiring diagrams, wiring and switches inside a timer or other switchblocks are drawn with lines that are thicker than the rest of the wiring. The small white circles all over the diagram are terminals. These are places where you can disconnect the wire from the component for testing purposes. If two wires cross on the diagram without a black dot, they are not connected. Switches may be numbered or lettered. Usually the terminals on the outside of the timer or switch are stamped or printed with markings that you will see on the wiring diagram. To test a switch, mark and disconnect all the wires.
For example, in figure 2-F, if you want to test the door switch, take power off the machine, disconnect the wires from it and connect one test lead to COM and one to NC. If it does, you know that contact inside the switch is good. Remember that for something to be energized, it must make a complete electrical circuit. You must be able to trace the path that the electricity will take, FROM the wall outlet back TO the wall outlet.
In this simplified circuit diagram, notice that only the heating elements operate on 220 volts.
Since the locking mechanism is interlocked with the heating circuit, the oven will not reach cleaning temperature either.Let's start at the lock motor and find out which switches feed electricity to it. Tracing the other lock motor lead, we first end up at the "C" terminal of the 4-position selector switch. Looking at the switch for the chart, the "C" to "LM" contacts are closed when the "clean" button is depressed on the switch. Power then leaves the thermostat through the "5" terminal, so we need to check for continuity between terminals "5" and "6" of the thermostat. Since it is a thermostatic switch, only heat will open the switch, so we only need to test it for continuity. They are shown in the diagram in their "normal state." So continuing with our circuit, if the locking motor is not turning, you need to check switch "B" for continuity between the "COM" and "NC" terminals. If there is no continuity, it might mean the switch is bad. It might also mean that the switch was not returned to its "normal" state the last time it was activated!You need to examine the switch carefully to determine what the problem is. If the locking motor stopped turning before the switch unlocked, you've got other problems. You will need to trace other circuits in the diagram to figure out what. From the "COM" terminal of switch "B," the circuit goes back through the door switch to L1. The door switch feeds several other oven circuits, too, so unless there's something else not working, we can eliminate that as the problem.
The door must be closed to close the switch that feeds electricity to the thermostats and heating circuit.To check for a wire break, you would pull each end of a wire off the component and test for continuity through the wire. You may need to use jumpers to extend or even bypass the wire; for example, if one end of the wire is in the control console and the other end in underneath the machine. It will then be up to you to figure out exactly where that break is - there is no magic way.
An ammeter is a safer way to test energized circuits if you have one, especially testing 220 volt circuits.
Occasionally, if the component is inexpensive enough, it's easier to just replace it and see if that solves the problem. Following is a primer on how to test each individual component you might find in any given oven.
Take all wires off the component and test continuity across it as described in section 2-4(b). Switches should show good continuity when closed and no continuity when open. NO means "normally open" and with the switch at rest, you will see no continuity through it. SELECTOR SWITCHBLOCKS A selector switchblock, located in the control panel, is a group of switches all molded into one housing. In your oven, a switchblock might be used to allow you to choose a cooktop heat setting, for example, or a cleaning cycle instead of a baking cycle. You must look at the wiring diagram to see which of the terminals will be connected when the internal switches are closed. Keep in mind, however, that you must also know which of the internal switches close when an external button is pressed. When you press one button on the switchblock, several of the switches inside may close at once.To test a switchblock, in addition to the wiring diagram, you must have a chart that gives you this info. Usually this is a part of the wiring diagram. Using the diagram and chart in figure 2-J, lets say we want to test contacts "T1" to "FM" for proper operation.
We see that with the "clean" button pressed, these contacts inside the switchblock should be closed.
Although error (fault) codes for most major brands may be found in Chapter 7, usually diagnosis consists of simply replacing circuit components until you find the bad one. Usually the problem turns out to be a bad oven sensor, stuck or defective keypad, ERC (clock) unit or a circuit board.
These can be tested and rebuilt or replaced as described in this chapter.2-6 (c) THERMOSTATIC CONTROLSA thermostat is simply a switch or a gas valve that opens and closes according to the temperature it senses. If there is an automatic oven cycle, main control thermostats must also be wired through the timer. And if there is a cleaning cycle, they must be either bypassed or adjusted for the higher temperatures of that cycle. That's where you start to get dual-control thermostats, thermostats with twelve leads, and other complexities. Some even control two levels of the same pilot. Main control thermostats are about the most expensive commonly-replaced parts in an oven. It should be the last thing you conclude, after you have checked out everything else in the system.The liquid inside the bulb and capillary of an oven thermostat is usually a mercury or sodium compound or some other such nasty and dangerous stuff. So when you replace an oven thermostat, do not cut open the capillary or bulb, and dispose of the old thermostat properly. The definition of "properly" varies between jurisdictions, but check with your appliance parts dealer or local fire department hazardous materials professionals.ADJUSTING THERMOSTATS The oven is adjusted by a small adjusting screw in the center of the oven thermostat valve stem. In other words, if you set the thermostat at 350 degrees, you want the heating system to cycle on if the temperature is below 340 degrees, and off when the temperature reaches about 360 degrees.
With nothing else in the oven, place it in the middle of the oven, where you can see it through the oven door glass.
The important thing to remember about clocks in an oven unit are that often the thermostat controls are first wired through the timer. Also, if you are troubleshooting a no heat complaint in an oven with an automatic cycle, the first step is always to check the timer controls. The woman who greeted me was the ultimate Susie homemaker; everything was spotless in HER kitchen. Including the oven, which looked new, but this gal swore she'd owned it since it was new 35 years before, and by golly she knew it inside and out and didn't know why two ovens out of three suddenly didn't work. You must have a wiring diagram to determine which terminals are connected when a switch inside the timer closes. Put a resistance meter across those terminals and advance the clock to determine if the switch is opening and closing.
If the clock motor doesn't run or the switches don't open and close as they are supposed to, replace the timer. If there are any special wiring changes, they will be explained in instructions that come with the new timer. Clocks and timers can usually be rebuilt. Ask your appliance parts dealer for details.2-6 (e) ELECTRIC HEATERS AND IGNITORSElectric heater elements and ignitors are tested by measuring continuity across them as described in section 2-5(b). Replace heater elements if they show no continuity.2-6 (f) RELAYSHeating elements use a lot of electricity compared to other electrical components. The switches that control them sometimes need to be built bigger than other kinds of switches, with more capacity to carry more electricity. The switches involved in running a heater or ignitor can be too big to conveniently put inside the control console or timer. Besides that, there are safety considerations involved in having you touch a switch that carries that much electricity directly, with your finger. The way they solve that problem is to make a secondary switch. A little switch activates an electromagnet, which closes a big switch that carries the heavier current load. Energize the unit only long enough to perform whatever test you're performing, then disconnect the power again. 3) If this manual advocates replacing the part, REPLACE IT!!
