So do magnets repel EMF radiation? A magnet is a component that consists of magnetized materials. These magnetized materials are able to produce magnetic fields. As the magnet exerts its magnetic force, it creates electromagnetic radiation. Therefore, magnets cannot repel EMF radiation.
A magnet attracts metals such as Iron, Nickel, and Cobalt. As energy passes through these metal materials, it reduces its force. However, some metals when magnetized can reduce EMF potency significantly, but it is because of the properties of the metal, not the magnetization of the metal. Depending on the materials used in making the metal, it may or may not block EMF radiation or reduce the effect of it.
To understand how magnets and EMF radiation work, we will focus on the magnetized material and its ability to reduce EMF levels.
There are typical materials which can shield electromagnetic fields. These materials include sheet metal, metal forms and metal screens. If a shield or mesh has some holes, they should be smaller than the wavelength of the radiation that you are attempting to block.
This is especially true of iron. A thick sheet of iron can almost completely block EMF radiation. If the sheet of iron is magnetized, it can still block EMF radiation, but not as effectively since it’s a magnet now.
To fully answer the question “do magnets repel EMF radiation?” you need to remember that magnets don’t block EMF radiation but metals that are magnetized can.
If you have a wide flat magnet attached to the refrigerator, you may wonder if it is repelling the EMF coming from your fridge? This can be tested using an EMF meter. When tested, it is found that the metal itself will reduce the radiation, but the presence of the magnet in some cases resulted in increased readings on the EMF meter.
Most refrigerator magnets are made of plastic and rubber with very weakly magnetized material. Mixing the magnetized iron material or the iron dust with rubber compound only forms a partial magnet. These fridge magnets do not repel electromagnetic radiation, nor do they reduce the force or effect of the EMFs coming from your fridge.
How Magnets Interact with EMF Radiation
The presence and use of electric and magnetic fields generates electromagnetic fields and electromagnetic radiation.
Though invisible, magnets can create their own force through other ferromagnetic material that attracts or repels other magnets. The ferromagnetic material attracts magnets and it is magnetized to become a magnet. These magnets create their own magnetic fields.
The force created by magnets makes electrons flow, while magnetic field force attracts metallic objects. The quantity of ferrite in an object affects its magnetic potential. The greater the quantity of ferrite, the higher the ferromagnetic property of the object is.
Magnets also contain superconducting elements forming electromagnetic compounds. The magnetic fields inside a superconductor element are very dangerous to individuals. Too much exposure to these magnetic fields have some health hazards.
Summary
Magnets and materials that are magnetized do not effectively repel or block EMF radiation. This is because, by their very operating properties, they create a magnetic field when they are used. Some items that are magnetized have more EMF repelling properties than others. That is because many metals block magnetic fields. Magnets attract some metals like iron, nickel, and cobalt, among others.
As electrical current passes through these metals, its force is reduced, and so is the amount of EMF radiation. Only very thick iron has been reported to be truly effective at repelling/blocking EMF radiation. For most metals, it is impossible to block EMF radiation.
The magnetized material that can shield electromagnetic fields includes a sheet of metal, metal forms and metal screens. A thick sheet of iron can partially repel EMF radiation, but if it’s magnetized it can’t because it’s magnetic itself.
