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. 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.
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. 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. 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.

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. 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). 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. Attention pacemaker wearers, welders and anyone wanting to shield their upper body from magnetic fields! Magnetic fields are the part of electromagnetic fields (EMFs) that penetrate concrete, steel and human bodies.
Artificial electromagnetic fields are caused by human activities and technologies (from appliances to cell phones to high voltage wires). Anything that’s plugged into a wall socket gives off an electromagnetic field (EMF) of 50-60 hertz, even if that appliance is turned off. Recently, the British Health Protection Agency found one of the causes of neuromas (tumors deep in the ear) are cordless phones.


That electric clock next to your head could be emitting a magnetic field of 5 to 10mG—even up to a yard away—the EMF equivalent of an electric power line! Neutralizes and harmonizes the 60-hertz field from any technologies that plug into a wall, making them safe to use. All electrical appliances produce electromagnetic fields which are damaging to our health. When the body is exposed to EMFs like in the picture above the electrical field of the body is disrupted causing our cells to function incorrectly.
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. 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. 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. 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. See below for products recommended for protection from the effects of EMF fields in the home produced by appliances.
The telephone receiver, the part held to your ear, carries a harmful south polar magnetic energy. Older style televisions and computer screens produce radio-frequency fields of 10,000-30,000 Hz (10-30 kHz) as well as 60 Hz fields. Typical electric appliances run at 50-60hz which is significantly higher than the earth's and our bodies magnetic fields which range between 7-10hz. These frequencies are severely incompatible with our bodies so when we enter their magnetic fields they disrupt our own. Shielding is certainly possible, but the shield must not hamper quick and easy access to the controls inside the box. Also, find out if there are other sources, such as wiring leading to the circuit box, nearby fluorescent lights, etc. 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. When EMFs come within proximity to our bodies they cause damage to the cells by disturbing their magnetic field.
New studies are even showing that each individual cell has its own magnetic field which builds up on our entire framework. Our own bodies magnetic field is at a very low level and therefore can be disrupted relatively easily. 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. Below we have prepared a table of common household items and rated them on a scale of 1-5 on how powerful and dangerous the electromagnetic field the device creates.
When we measure a healthy body we will find the magnetic field has a frequency of about 7-10hz. Studies have shown when we come in contact with stronger EMFs they disrupt each of our bodies cells magnetic fields and increase the bodies voltage. With snug fitting shapes, get as much as 75% attenuation of the magnetic field with one thickness. What is interesting is when the earth's magnetic field was measured in the 1950s it frequency was recorded at 7.83hz and has been changing slightly over time. When your cells magnetic fields are altered by strong EMFs they cannot function correctly. 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 122°F. Simple to use: just cut to desired length with a heavy scissors, peel the protective backing and press into place! You can see that our bodies and the earth's magnetic field operate at the same frequency along with all other living things on this earth. This is the same case with our cells, they are designed to operate with a magnetic field of 7-10hz but when influenced by EMFs their magnetic frequency rises and they start operating at a frequency they are not capable of handling. The problem occurs with too much exposure or at too high a level of EMFs where the cells get so disrupted they cannot re-balance their magnetic field and continue functioning incorrectly.
