MagnetShield. First line of defence for shielding strong static magnetic fields from magnets & speakers. Also for small transformers and motors. Strong magnetic fields are harder to shield because they tend to “saturate” the shielding material. This 4″ wide sheet Iron alloy is a hefty .010″ thick and has an exceptionally high magnetic saturation of 21400 Gauss and maximum permeability of 4000. Tin plated for excellent corrosion resistance and better conductivity, it can be soldered or painted.
– The magnets will be attracted to the MagnetShield (this is true of ALL magnetic shielding alloys). If you want to shield 2 adjacent magnets from each other, each magnet should have its own shield.
– The size, shape, and position of the shield all matter in terms of shield performance. For example, larger shields are better than small shields. Closer to the magnet is better than farther from the magnet. And parallel to the magnetic field lines is better than perpendicular to them.
– You will likely need more than one layer of shielding material, depending on the strength of your magnets. More layers = more attenuation.
