what is ferrite magnet ?
Ferrite is a ferromagnetic metal oxide. As far as electrical properties are concerned, the resistivity of ferrite is much larger than that of metal and alloy, and there is a high dielectric property. The magnetic properties of ferrite also exhibit high permeability at high frequencies. As a result, Ferrite has become a high-frequency weak area of use of a wide range of non-metallic magnetic materials. Because of the low magnetic energy stored in the Ferrite unit volume, the saturation magnetization is also lower (usually only the pure iron 1/3~1/5), thus limiting its application in the field of low-frequency strong power and high power requiring higher magnetic density.
