MagnetShield - Magnetic Field Shielding Alloy (For speakers & static magnets)
MAGNETSHIELD
First line of defence for shielding strong magnetic fields from magnets, speakers, small transformers and motors. Strong magnetic fields are harder to shield because they tend to "saturate" the shielding material. This 4" wide Sheet 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.
Applications Notes:
– The magnets will be attracted to the shield (this is true of ALL magnetic shielding alloys). If you want to shield 2 adjacent magnets from eachother, 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.
MagnetShield typically reduces fields up to a factor of 2 or 3 depending on size/shape of the shield. Can be used in multiple layers. Annealing is not necessary with this material.
