BH Curves of Ferrite Magnets, Ceramic Magnets
Ferrite magnets are a kind of metallic oxide with ferromagnetic property, also be called as ceramic magnets . In aspect of electrical characteristic, ferrite magnets have higher electrical resistance and stronger dielectric property than that of metal and magnetic alloy. Besides, ferrite magnets have higher permeability in high frequency. Therefore, it has become a kind of nonmetal permanent magnetic material with wide applications in area of high frequency and weak current.

With high electricity resistance and its property of semiconductor, ferrite permanent magnets effectively work in magnetic circuit of big air gap, because of eddy-current loss and strong coercive force. They are particularly suitable for making small generator and electric motor.
