A circuit breaker box (or fuse box) in the bedroom, living room, kitchen, or other living space can be a real problem.
If you are handy, you can use the magnetic shielding materials listed below to make your own hinged shield. Another alternative is to mount the Giron directly on the wall and cover it with these attractive interior window shutters. GIRON Magnetic Shielding Film, which does not contain Nickel, is unlike any other magnetic shielding material available on the market today. Suitable for small shields on magnets, motors, speakers and appliances such as refrigerators, vacuum cleaners etc. We have teamed with the design and engineering division of the Giron manufacturer to offer start-to-finish magnetic shielding solutions for residential, commercial, and industrial buildings. Enjoy the confidence of an experienced team to obtain excellent results, lowest cost, and on-time delivery. Used for years in industry to shield delicate electronic components from EMFs, this 80% Nickel alloy magnetic shielding foil is now available at affordable prices for home and office use. Because we offer so many different matrials, of different widths, the easiest way to order rolled goods is by specifying how long the piece of material will be. The amount of shielding that you will achieve depends on many factors, including the size and shape of the shield. When using a flat shield on a wall, floor, or ceiling to shield a source of field that is close to the shield (within 8 inches), plan to cover an area that extends at least to the 2 mG line. 1- Using your gaussmeter, slide along the surface of the wall to locate the hot spot to be shielded. 2- Now slide the gaussmeter to the right, to the left, up, and down to identify how far you must shield to get to the 2 mG line. Make sure to check for additional sources of magnetic field (lights, wiring, appliances and so on), that may be located inside adjacent walls, floor, ceiling or within the same room. Click here for a short instructional video on doing a magnetic field survery for shield design. While the special alloys in Magnetic Shielding Foil, Mag-Stop Plates, Joint Shield, and Metglas, exhibit high magnetic permeability, there are many factors which affect the amount of magnetic shielding you will achieve by using these materials. Because we have no control over many of these factors, we cannot and do not guarantee any specific shielding performance for a specific application of these materials. 3] In general, you will extend the shield at least 2 feet beyond the size of the circuit box (or other fairly concentrated source), in all directions. 5] Also remember that you will achieve the greatest % reduction up close to the center of the shield (where the field is strongest anyway). In the end, some experimenting is often necessary to ensure proper shield thickness and placement. Joint-Shield can also be used by itself as an excellent magnetic shielding material when a 4" width and adhesive backing is desirable (wrap it around wiring and conduit, speaker magnets, even small appliances like shavers and hair dryers!). Combining high performance nanocrystalline magnetic shielding alloy sandwiched between layers of clear PET to achieve good performance and easy handling. First line of defense for shielding strong magnetic fields from magnets, speakers, small transformers and motors. Better: One or more layers of MagnetShield (closest to the source of field), followed by one or more layers of a high permeability material such as Joint-Shield or MagStop Plate. For shielding jobs where you don’t need a high attenuation, this unique material is just the ticket. Attention pacemaker wearers, welders and anyone wanting to shield their upper body from magnetic fields! Made with 10mm diameter, shiny galvanized, 16g round mild steel rings which are butted closed.
At last, we are proud to offer wiring which actually reduces EMF emissions to extremely low levels. The result is a high quality wire with the lowest possible EMF emissions (over 90% reduction compared to standard wire). MµCord™ flexible “appliance cord style” for re-wiring lights and appliances, making extension cords, etc.
Holland Shielding Systems BV has developed a range of products and turnkey solutions to shield from magnetic fields. Its main applications are in shielding flexible cables with small diameters and rapid and flexible solutions to problems at low field strengths.
Turnkey solution for the shielding of cables and cable routes in hospitals, laboratories and workplaces. If you want to perform a measurement on site to determine whether a shield is necessary you can also contact us. Worldwide leading manufacturer of EMC (electromagnetic compatibility), EMI (electromagnetic interference) and RFI(radiofrequency interference) shielding solutions. Keep up to date with the latest developments in Holland Shielding Systems BV by signing up for our newsletter. Many of us who experiment with magnetic devices understand how hard it is to create a magnetic shield. This is accomplished using a magnetic shielding comprising various layers of a highly magentizable alloy. Reducing electromagnetic noise is a key prerequisite for many high-precision experiments in physics – but also in biology and medicine. Peter Fierlinger’s team is currently developing an experiment to determine the charge distribution in neutrons -referred to by physicists as the electric dipole moment. Yet, there are still phenomena that cannot be adequately explained: Gravity, for example, is not even considered in this model. Physicists therefore attempt to create short-lived conditions as were prevalent in the early universe using particle accelerators like the Large Hadron Collider (LHC) at CERN. In addition to scientists of TU Munchen, physicists of the Physikalisch-Technischen Bundesanstalt Berlin, the University of Illinois at Urbana-Champaign, USA, the University of Michigan, USA, and IMEDCO AG in Switzerland contributed to the experimental setup and measurements of magnetic attenuation. While on Earth, the planet protects us from space radiation and cosmic rays with its magnetic field.
NASA along with its partners is exploring the possibility of using superconducting magnets to generate magnetic fields around space probes and space habitats to protect them from space radiation and cosmic rays. The NASA Innovative Advanced Concepts program is funding this study on high temperature superconductor technology as an active radiation shielding.


The shield would use superconducting magnetic tape attached to flexible material like Kevlar. Further study is needed to determine the total radiation experienced inside the magnetic shield, said Westover. Although the concept seems promising, issues such as structure required to hold the coils, and the energy required for generating a magnetic field strong enough to protect the crew, are yet to be overcome. Siddharth Raval is a masters student in Mechanical Engineering at University of New Brunswick. MuFerro combines permeable and satiety characteristics which makes it extremely suitable for screening low-frequent magnetic fields. Apart from their negative impact on health, strong magnetic fields can disturb or damage electronics in the direct surroundings of the field.
Due to space restrictions, one of our customers was forced to create a workplace in a room which had formerly been used as a warehouse and that was located above power transformers. The graph below show the magnetic fields in nano Tesla or 10-5 Gauss before and after the magnetic shielding was installed.
If you want a quote for a low-frequency magnetic shielding with (MuFerro ™ 6800) we ask you to send a drawing of the room concerned.
China Good Quality Modular RJ45 Jack, RJ45 with Transformer and Magnetic RJ45 Jack International Trade Site. Strong magnetic field emissions (depending on how much electric current is flowing) and electric field emissions can make the nearby area hazardous to occupy, especially for long periods. Suitable for high field strength applications requiring high saturation and good permeability, it is both thin and strong, and unlike Mu-metal™ it is very tolerant to bending or shaping without losing its shielding properties.
Cuts neatly with snips or sheet metal tools, and can be used either flat or molded into shapes for best performance.
The 30" wide "fully hydrogen annealed" plates offer the best shielding available (up to 10 times the shielding effectiveness of stress-annealed alloy) and should not be soldered, welded, or heated in any way.
The list of such factors includes: size and shape of the source of the magnetic field, size and shape of the shielded area, seams in the shielding material, frequency of the magnetic field, distance from shield to source, orientation of shield to the source, thickness and heat treatment of shielding material, etc. Also, note that foils, ribbons and plates, once cut by us to your specifications, are not refundable. Remember to make measurements under various conditions, as the readings will change according to how much electric current is flowing at the time of the reading.
This will influence the choice for thickness of the Mag-Stop Plate shield, or the number of layers used. In other words, the field will be stronger at the edge of the shield as compared to having no shield at all.
This occurs when the Earth's magnetic field (about 400 mG) interacts with a large shield, reducing its effectiveness, unless special "high saturation" (MagnetShield) shielding alloys are incorporated into the design. Joint-Shield can be shaped by hand, without the need for special tools, but watch the sharp edges.
Very light weight and flexible, easily trimmed with scissors this material will provide good high frequency magnetic shielding for moderate to low intensity fields below 1000 kHz.
Strong magnetic fields are harder to shield because they tend to "saturate" the shielding material. If you want to shield 2 adjacent magnets from eachother, each magnet should have its own shield. Only 0.010 inch thick, PaperSHIELD is flexible and can be easily cut with a scissors and shaped by hand into simple or very complex shapes. Replacing existing wire with MµCord is likely to be much less costly, more effective, and probably more convenient than shielding. Simply cut wire to desired length and add a plug to one end, or plug one end and socket on the other.
For more information, click on one of the following magnetic shielding products or magnetic shielding solutions. Here on the Earth, we are permanently exposed to both natural and artificial magnetic fields. The ensuing magnetic attenuation results in a residual magnetic field inside the shield that is even smaller than that in the depths of our solar system. In fundamental physics, the highest degree of magnetic shielding is essential when making precision measurements of miniscule effects in phenomena that drove the early development of our universe. Neutrons are nuclear particles that have a tiny magnetic moment but are electrically neutral. The Standard Model describes the characteristics of all known elementary particles to a high degree of precision. The Standard Model also fails to predict the behavior of particles at very high energies as they prevailed in the early universe. They smash particles into each other at high energies, in particular to create new particles.
Thus, even small deviations in particle characteristics could provide evidence for new, previously unknown particles. Funding was provided by the German Research Foundation (DFG) in the context of the Priority Program SPP 1491 and the Custer of Excellence Origin and Structure of the Universe.
No dangerous smart meter transmissions will bother them while they occupy this magnetism free zone.
NASA scientists are now working on an analogous approach to protect spacecraft from space radiation outside of Earth’s protective envelope. NASA JSC is performing this research along with Advanced Magnet Lab (AML), a Florida based company with expertise in superconducting magnets.
Current is passed through tape coils, resulting in a perpendicular expansion from Lorentz forces that would open it from collapsed configuration to large coils which surround the habitat.
Space radiation has been a hurdle to long duration human space exploration almost since human spaceflight began.
His research is focused towards the study of "Rotor Dynamics of Industrial Polymer Mixers (Flow Induced Vibrations)", which is a multi-disciplinary research combining Structures, Vibrations, and Fluid Dynamics disciplines. There is such a think as electric propulsion – it works by creating a directed flow of ions. After the magnetic fields were noticed by flickering computer displays, we were asked to carry out a magnetic field measurement. We will do a strict pre-shipment quality-check and package the items properly to ensure a safe shipment.


Product pictures may not reflect its original appearance due to aberration, environment etc.

Shielding is certainly possible, but the shield must not hamper quick and easy access to the controls inside the box. It’s a picture (or poster) in a nice frame, with high performance Giron shielding material behind the picture. We'll help you find the right solution, saving time, money, and creating satisfied customers! Now you can simply replace your Switch Plate or Outlet Cover with these custom shielded ones. So, for example, if you order 22 linear feet of a material, you will get a piece that is 22 feet long x the width of the material. Hydrogen annealed plates have 2 small holes pre-drilled near one end which may be used for mounting.
Also, find out if there are other sources, such as wiring leading to the circuit box, nearby fluorescent lights, etc.
Most would recommend that you achieve readings of 2.5 mG or less in areas where people will be spending a lot of time.
This is a generous .010" thick, fully hydrogen annealed magnetic shielding alloy with adhesive backing (rated 0 - 200°F) on one side. This 4" wide foil is a hefty .010" thick and has an exceptionally high magnetic saturation of 21400 Gauss and maximum permeability of 4000.
High saturation and moderate permeability make this ideal for shielding weak magnets, or stronger magnets with many layers of shielding.
Composed of individual metal links which give good flexibility and plenty of air circulation. For example, if you don’t need the head covering, you could move those links to achieve more shoulder or heart coverage.
An international team of physicists has now developed a shielding that dampens low frequency magnetic fields more than a million-fold. The new, nearly magnetic field free space provides the requisite conditions for improving measurements of the electric dipole moment by a factor of 100.
And, it provides no explanation for why matter and antimatter from the Big Bang did not annihilate each other completely, but rather a small amount of matter remained from which we and our surrounding, visible universe are ultimately formed. He is currently associated with Space Safety and Sustainability Working Group at Space Generation Advisory Council, where he and his team is working on Space Debris Removal mission design. It is rather slow but builds up over time and is therefore useful for long duration robotic missions.
These fields are generated by installations in which high currents flow, for example transformer rooms , power lines, busbar systems and nearby high-voltage cables. It was found that the magnetic field-strenght was far above the standard referred to above: it was 750nTesla. Buyer should return the good with its original packaging, accessories, manuals, warranty cards, and all other items enclosed (Gift exception) in the exact condition in which it was received. Magnetic field reduction is 30 to 60% up close to the surface, depending on wire configuration.
Can be formed into magnetic barriers on cellular phones, microwave ovens, doorbell transformers, VDTs, buried wiring, and more.
Just right when you need to cut magnetic shielding materials including Giron, MagnetShield , and Magnetic Shielding Foil.
Simply butt the Mag-Stop plates tightly together, and "tape" over the seam with Joint-Shield high permeabilty alloy.
Tin plated for excellent corrosion resistance and better conductivity, it can be soldered or painted. This material is particularly suited for achieving precise levels of partial shielding as you can add exactly the right number of layers to achieve the desired result. Using this mechanism, they have created a space that boasts the weakest magnetic field of our solar system. On top of this come local magnetic fields generated by transformers, motors, cranes, metal doors and the like.
The magnetic field was reduced by installing an umbrella construction of MuFerro™ 6800. With snug fitting shapes, get as much as 75% attenuation of the magnetic field with one thickness. This method offers much less bulk and better appearance than the old overlap technique and provides excellent shielding integrity. What I was hoping to find in this article was a discovery of a shielding material that does not magnetize.
In our tests, a 2-foot section of Giron in a 24x36 inch frame provided 50-70% reduction of magnetic field. Works with AC or DC magnetic fields (0-1000 Hz), and will tolerate temperatures from 32° to 140°F. Simple to use: just cut to desired length with a heavy scissors, peel the protective backing and press into place!
Peel and stick adhesive on the other side permits easy and semi-permanent mounting almost anywhere. If you need a shield larger than what is suggested here, just contact us, we will be happy to assist you. Laminated with a 0.005 inch glass reinforced polypropylene tape which is UV sensitive, cover if installation is exposed to direct sunlight. Make sure you have enough room between outlet and nearby moldings for these larger than standard covers.
