Ferrite magnet
Anisotropic ferrite magnet
Ferrite magnets have a high coercive force, so there is no demagnetization.Since it is a boiled magnet (ceramic magnet), it has excellent corrosion resistance and is suitable for flat molds, but on the other hand, it has the disadvantage of being easily cracked.In addition to conventional audio speakers and headphones, the demand for automobile motors and generators is further increasing due to the weight reduction (one-half to one-third of the conventional one) due to technological innovation.Since ferric oxide, which is a raw material, is abundant, it can be provided at the lowest price among current magnets.It can be divided into two types: anisotropic ferrite magnets (Anisotropic Sr-Ferrite) and isotropic ferrite magnets (Isotropic Ba-Ferrite).
