The magnetic material used on any occasion is ferrite magnetic material
Divided into ferrite permanent magnetic ferrite, magnetic materials, magnetic materials, magnetic materials, rotary moment, piezomagnetic material. About the scope and properties of various ferrites
A compound having a six axis structure with uniaxial anisotropy. Mainly barium, strontium, lead three ferrites and their composite solid solution. Equal magnetic and anisotropic magnetic separation. Due to the disappearance of the external magnetization field, the ferrite can retain a strong permanent magnetic remanence for a long time and can be used to produce a stable magnetic field in the external space. It is widely used, for example, in various types of electric meters, generators, telephones, loudspeakers, televisions and microwave devices, as permanent magnets.
Ferrite is a ferromagnetic metal oxide. As far as electrical characteristics are concerned, ferrite resistivity is much larger than metal and alloy magnetic materials, and has higher dielectric properties. The magnetic properties of ferrites also exhibit high permeability at high frequencies. As a result, ferrite has become a high frequency, weak current field of non-metallic materials widely used
