Ferrite magnet is a ferromagnetic metal oxide. On the electrical characteristics, the ferrite resistivity than metal, alloy magnetic material is much greater, but also a higher dielectric properties. Magnetic ferrite can also have a higher performance at high frequency permeability. Thus, a wide ran

The ancient Greeks and Chinese people find nature a kind of natural magnetization of stone, called "magnet." This stone can magically pick up small pieces of iron sheet, and after swinging freely always point in the same direction. Early sailors put this magnet as its earliest compass to identify th
