Though many people have been thought to have contributed to the discovery of this phenomenon, it is Michael Faraday who is credited with first making the discovery in 1831. Whereas it was already known at this time that an electric current produced a magnetic field, Faraday demonstrated that the reverse was also true.

I wrote the following as a promotional piece for my book Strange Electromagnetic Dimensions, which is due out in November. What we perceive with our eyes is less than one percent of the electromagnetic (EM) spectrum, the range of wavelengths over which EM radiation extends. Every living creature on the planet is immersed in a sea of EM radiation from both natural and artificial sources. As we continue to “electrify” the planet at an alarming rate through technological means, natural sources of EM radiation that have been present throughout our entire evolution and to which we are synchronized biologically are gradually being drowned out by artificial sources of EM radiation. The World Health Organization (WHO) remains adamant in its position that “to date there is no evidence to conclude that exposure to low level [non-ionizing] electromagnetic fields is harmful to human health.” And yet an abundance of scientific research argues otherwise, some of it dating back more than half a century. There’s compelling evidence that such exposure suppresses production of the hormone melatonin by the pineal gland, resulting in disruption of the sleep-wake cycle and an increased risk of developing certain cancers. Radar, which uses beams of pulsed microwaves to “sense” distant objects, was developed to perfection during the Second World War. In the 1970s, Eastern European and Soviet researchers began to use the term “radio-wave sickness” to refer to a clinical syndrome in those occupationally exposed to EM fields, particularly RF fields.
A growing number of people around the world are reporting symptoms characteristic of radio-wave sickness. More debilitating still is electromagnetic hypersensitivity (EHS), a condition which emerged during the 1980s and has been increasing rapidly in incidence ever since. If indeed we humans are sensitive to both natural and artificial EM fields, to what do we owe such sensitivity? In addition to being a celebrated ability of homing pigeons, magnetoception has been observed in turtles, mice, mole rats, bats, fruit flies, honey bees, and even bacteria. Although magnetoception could hardly be classified as a paranormal faculty, there are an abundance of instances whereby the paranormal and electromagnetism intersect. The buildup of static on the body and the experience of making electrical devices go haywire for no apparent reason are both key symptoms of a condition called high voltage syndrome (HVS).
A fifty-year-old electric person from New Zealand’s Kapiti Coast, named Kate R, mentioned to me in an email that streetlamps “go on and off” when she approaches them, a phenomenon known as streetlamp interference (SLI).
The phenomena claimed by Kate and other electric people are similar to those reported in connection with poltergeist agents.
The message is clear: by continuing to pollute and thereby alter our EM environment, we are also altering ourselves.

Electromagnetic radiation, the larger family of wave-like phenomena to which visible light belongs (also known as radiant energy), is the primary vehicle transporting energy through the vast reaches of the universe.
The tutorial initializes with a sine function simulating electromagnetic wave propagation traversing from left to right across the window. An electromagnetic wave travels or propagates in a direction that is oriented at right angles to the vibrations of both the electric (E) and magnetic (B) oscillating field vectors, transporting energy from the radiation source to an undetermined final destination.
Whether taking the form of a signal transmitted to a radio from the broadcast station, heat radiating from a fireplace, the dentist's X-rays producing images of teeth, or the visible and ultraviolet light emanating from the sun, the various categories of electromagnetic radiation all share identical and fundamental wave-like properties. The classical schematic diagram of an electromagnetic wave presented in Figure 1 illustrates the sinusoidal nature of oscillating electric and magnetic component vectors as they propagate through space. A standard measure of all electromagnetic radiation is the magnitude of the wavelength (in a vacuum), which is usually stated in units of nanometers (one-thousandth of a micrometer) for the visible light portion of the spectrum.
The speed of propagation c can be the speed of sound *or* the speed of light and radio waves. The notation "eV" stands for electron-volts, a common unit of energy measure in atomic physics. A multimeter is an electrical instrument capable of measuring voltage, current, and resistance. Analog multimeters tend to be less expensive than digital multimeters, and more beneficial as learning tools for the first-time student of electricity.
In all the experiments in this book, you will be using some sort of test equipment to measure aspects of electricity you cannot directly see, feel, hear, taste, or smell. Voltage is the measure of electrical "push" ready to motivate electrons to move through a conductor. If your meter is a manual-range type, and the selector switch has been set to a high-range position, the indication will be small.
Be sure to measure more than one size of battery, and learn how to select the best voltage range on the multimeter to give you maximum indication without over-ranging. Now switch your multimeter to the lowest DC voltage range available, and touch the meter's test probes to the terminals (wire leads) of the light-emitting diode (LED). Although your multimeter is capable of providing quantitative values of measured resistance, it is also useful for qualitative tests of continuity: whether or not there is a continuous electrical connection from one point to another.
Digital multimeters set to the "resistance" mode indicate non-continuity by displaying some non-numerical indication on the display. Use your meter to determine continuity between the holes on a breadboard: a device used for temporary construction of circuits, where component terminals are inserted into holes on a plastic grid, metal spring clips underneath each hole connecting certain holes to others. An important concept in electricity, closely related to electrical continuity, is that of points being electrically common to each other. Like continuity, commonality is a qualitative assessment, based on a relative comparison of resistance between other points in a circuit.
If the needle points very close to zero, you need to select a lower resistance range on the meter, just as you needed to select an appropriate voltage range when reading the voltage of a battery. If you are using a digital multimeter, you should see a numerical figure close to 10 shown on the display, with a small "k" symbol on the right-hand side denoting the metric prefix for "kilo" (thousand). When you touch the meter probes to the resistor terminals, try not to touch both probe tips to your fingers.

You may safely measure the resistance of your own body by holding one probe tip with the fingers of one hand, and the other probe tip with the fingers of the other hand. Move the probe tips closer together on the black mark and note the change in resistance value.
Connect your meter to the terminals of a cadmium-sulphide (CdS) photocell and measure the change in resistance created by differences in light exposure. Experiment with measuring the resistance of several different types of materials, just be sure not to try measure anything that produces substantial voltage, like a battery. From this experiment on, a multimeter is assumed to be necessary and will not be included in the required list of parts and materials. This is the simplest complete circuit in this collection of experiments: a battery and an incandescent lamp. If there is a "break" (discontinuity) anywhere in the circuit, the lamp will fail to light. Using your multimeter set to the appropriate "DC volt" range, measure voltage across the battery, across the lamp, and across each jumper wire.
Construct the same circuit on a breadboard, taking care to place the lamp and wires into the breadboard in such a way that continuity will be maintained.
Experiment with different configurations on the breadboard, plugging the lamp into different holes. Here there is no "shorting" wire present on the breadboard, yet there is a short circuit, and the lamp refuses to light.
Short circuits are generally to be avoided, as they result in very high rates of electron flow, causing wires to heat up and battery power sources to deplete.
The most common way to measure current in a circuit is to break the circuit open and insert an "ammeter" in series (in-line) with the circuit so that all electrons flowing through the circuit also have to go through the meter. Some digital meters, like the unit shown in the illustration, have a separate jack to insert the red test lead plug when measuring current. When an ammeter is placed in series with a circuit, it ideally drops no voltage as current goes through it. Ammeters are generally protected from excessive current by means of a small fuse located inside the meter housing. You may test the condition of a multimeter's fuse by switching it to the resistance mode and measuring continuity through the test leads (and through the fuse).
Build the one-battery, one-lamp circuit using jumper wires to connect the battery to the lamp, and verify that the lamp lights up before connecting the meter in series with it. For a 6-volt battery and a small lamp, the circuit current will be in the range of thousandths of an amp, or milliamps. Insert a spare piece of wire into the hole you just pulled the other wire or terminal out of. Connect the ammeter between the two unconnected wire ends (the two that were hanging in mid-air). Again, measure current through different wires in this circuit, following the same connection procedure outlined above.
At the recommended resistance values, there will still be a small amount of measurement error due to the "impact" of the meter, but not enough to cause serious disagreement with calculated values. Select a resistor from the assortment, and measure its resistance with your multimeter set to the appropriate resistance range.
Taking the measured figures for voltage and resistance, use the Ohm's Law equation to calculate circuit current. Taking the measured figures for voltage and current, use the Ohm's Law equation to calculate circuit resistance. Finally, taking the measured figures for resistance and current, use the Ohm's Law equation to calculate circuit voltage. Substitute different resistors in the circuit and re-take all resistance, voltage, and current measurements. What you should find is a marked difference between measured current and calculated current: the calculated figure is much greater. To make things more interesting, try measuring the lamp's resistance again, this time using a different model of meter. Using a different ohmmeter, the lamp will probably register as a different value of resistance. The thermometer should be as small as possible, to facilitate rapid detection of heat produced by the resistor. Measure each resistor's resistance with your ohmmeter, noting the exact values on a piece of paper for later reference. Connect the 330 Ω resistor to the 6 volt battery using a pair of jumper wires as shown in the illustration. All points of contact along the upper wire in the illustration (colored red) are electrically common to each other.
Now that you've measured and recorded resistor resistance, circuit voltage, and circuit current, you are ready to calculate power dissipation. Try calculating power in this circuit, using the three measured values of voltage, current, and resistance.
The power rating of any electrical component does not tell us how much power it will dissipate, but simply how much power it may dissipate without sustaining damage.
Caution: keep the 10 Ω resistor away from any flammable materials when it is powered by the battery!
You may not have enough time to take voltage and current measurements before the resistor begins to smoke. What trend do you notice with the resistor's value as it is damaged more and more by overpowering? Build a one-battery, one-switch, one-lamp circuit as shown in the schematic diagram and in the illustration. Measure voltage across the battery, across the switch (measure from one screw terminal to another with the voltmeter), and across the lamp with the switch in both positions. Magnet wire is a term for thin-gauge copper wire with enamel insulation instead of rubber or plastic insulation.
Wrap a single layer of electrical tape around the steel bar (or bolt, or mail) to protect the wire from abrasion. After you've wrapped several hundred turns of wire around the rod, wrap a layer or two of electrical tape over the wire coil to secure the wire in place. When electric current goes through the coil, it will produce a strong magnetic field: one "pole" at each end of the rod.

With the electromagnet energized (connected to the battery), place a permanent magnet near one pole and note whether there is an attractive or repulsive force. Electromagnetism has many applications, including relays, electric motors, solenoids, doorbells, buzzers, computer printer mechanisms, and magnetic media "write" heads (tape recorders, disk drives).
You might notice a significant spark whenever the battery is disconnected from the electromagnet coil: much greater than the spark produced if the battery is simply short-circuited. Connect the multimeter to the coil, and set it to the most sensitive DC voltage range available. If using an analog multimeter, be sure to use long jumper wires and locate the meter far away from the coil, as the magnetic field from the permanent magnet may affect the meter's operation and produce false readings.
At one time, electricity was a humble offering, providing humanity with unnatural light that did not depend on gas lamps or kerosene lanterns.
Known as Faraday’s law, it states that “The induced electromotive force (EMF) in any closed circuit is equal to the time rate of change of the magnetic flux through the circuit”. In short, he proved that one could generate an electric current by passing a wire through a magnetic field. One of the most widely known uses is in electrical generators (such as hydroelectric dams) where mechanical power is used to move a magnetic field past coils of wire to generate voltage. This tiny portion of the EM spectrum, called visible light, consists of the colors red through violet. Common sources of artificial EM radiation include cellphones and cellphone base stations, power lines, electrical appliances in the home, and TV and radio transmitters.
We seem to forget that the use of electricity on a large-scale is a fairly new development in the history of humanity, having only really started in the 20th century with the establishment of power stations and electricity grids. On the one hand, it’s improved our standard of living in ways our ancestors would never have dreamed possible.
Studies have revealed a connection between exposure to EM fields and such health problems as brain cancer, leukemia, and depression. There’s evidence, too, that EM field exposure can induce in the body a state of chronic stress, which in turn compromises the efficiency of the immune system and increases one’s susceptibility to illness. In the years following the War, the finding emerged that radar operators have a tendency to suffer from health problems that include internal bleeding, leukemia, jaundice, cataracts, headaches, brain tumors, and heart conditions. The symptoms they listed for radio-wave sickness include headache, increased fatigability, increased irritability, dizziness, loss of appetite, sleepiness, difficulties in concentration or memory, depression, emotional instability, and rashes.
I myself suffered from symptoms that I ascribe to radio-wave sickness when, for a period of eight months beginning in mid-2012, I lived in a house fitted with a smart meter.
Those afflicted with EHS find they become ill when exposed to virtually any form of artificial EM radiation, whether it’s from a cellphone, a washing machine, or power lines. A series of experiments conducted throughout the 1970s by a British biologist named Robin Baker, one of which involved taking blindfolded schoolchildren on bus trips throughout the countryside and asking them to point in the direction of “home” once the bus had reached its destination, showed that humans most likely possess a magnetic sense of direction like that of other animals, albeit one that operates on a subconscious level and is relatively weak.
Many alleged psychics, including the British healer Matthew Manning and the Israeli-born spoon bender Uri Geller, suffered at a young age a severe electric shock from mains electricity. Those afflicted with HVS are termed “electric people.” Besides lightning strike and electric shock as initiators of HVS, the condition can arise after suffering an emotional crisis or as a side effect of severe illness.
Mars’s small size could be way its field stopped but then smaller mercury has a strongish field.
Today, it has grown to become the basis of our comfort, providing our heat, lighting and climate control, and powering all of our appliances, be they for cooking, cleaning, or entertainment. In practice, this means that an electric current will be induced in any closed circuit when the magnetic flux (i.e. To test this hypothesis, Faraday wrapped a piece of metal wire around a paper cylinder and then connected the coil to a galvanometer (a device used to measure electric current). Making up the remainder of the spectrum are extremely low frequency (ELF) waves, radio waves, microwaves, infrared, ultraviolet, X-rays, and gamma rays.
Natural sources include the earth’s magnetic field and ELF waves generated by global lightning activity. Computers, MRI machines, refrigerators, and bomb disposal robots—all of these devices require electricity to operate.
Although it’s true that microwaves, which belong to the radio frequency (RF) portion of the EM spectrum, can heat and therefore damage bodily tissue, the adverse health effects experienced by the radar operators were non-thermal in origin.
Symptoms of EHS include fatigue, anxiety, concentration and memory difficulties, digestive disturbances, ringing in the ears, and dermatological issues such as redness, tingling, and burning. What makes this evidence significant is that numerous living things endowed with magnetoception—the ability to detect a magnetic field to perceive direction, altitude, or location—contain magnetite crystals in their bodies. The development of psychic abilities is a claim also common among lightning strike survivors.
In 1920, thirty-four convicts at Clinton Prison, Dannemora, New York, developed what was described as “peculiar static electric power” after becoming ill with botulism poisoning. Such disturbances typically involve objects being thrown about and banging and rapping sounds but can also take the form of electrical devices malfunctioning for no apparent reason. Davidson - National High Magnetic Field Laboratory, 1800 East Paul Dirac Dr., The Florida State University, Tallahassee, Florida, 32310. And beneath most of the machines that make it possible is a simple law known as Electromagnetic Induction, a law which describes the operation of generators, electric motors, transformers, induction motors, synchronous motors, solenoids, and most other electrical machines.
He then moved a magnet back and forth inside the cylinder and recorded through the galvanometer that an electrical current was being induced in the wire.
Although we cannot see these energies, they are an ever-present part of our environment and affect our minds and bodies in profound ways. More and more evidence is accumulating to suggest that EHS involves a response on the part of the immune system in a similar manner to that of a conventional allergic reaction.
Many survivors further claim that electrical devices go haywire whenever they touch or go near them, and that their bodies have an unusual tendency to become highly charged with static electricity. Most parapsychologists view poltergeist phenomena as instances of recurrent spontaneous psychokinesis (RSPK), which is equivalent to saying that the subconscious mind of the agent is responsible. Scientifically speaking it refers to the production of voltage across a conductor (a wire or similar piece of conducting material) that is moving through a magnetic field.
This applies whether the field itself changes in strength or the conductor is moved through it. He confirmed from this that a moving magnetic field was necessary to induce an electrical field, because when the magnet stopped moving, the current also ceased.
