introduction:

ferrite (ferrites) ferrite is a non-metallic magnetic material, also called iron oxide. It is made up of trioxylate
Iron and one or more other metal oxide (e.g. nickel oxide, zinc oxide, manganese oxide, magnesium oxide, barium oxide, strontium oxide
Etc.) prepared and sintered. Its relative permeability can be as high as several thousand, its resistivity is 1011 times that of metal, and its eddy current loss is small, which is suitable
In the manufacture of high-frequency electromagnetic devices. Ferrite has five types: hard magnetic, soft magnetic, moment magnetic, spin magnetic and pressure magnetic. Formerly known as iron oxide magnet or iron
Oxygen is also called magnetic porcelain because its production process and appearance are similar to ceramics. Ferrite is iron and one or more other suitable
Composite oxide of metal elements. Properties belong to semiconductor, usually used as magnetic medium, ferrite magnetic material and metal or
The most important difference between alloy magnetic materials is conductivity. Generally, the resistivity of the former is 102~108 Ω · cm, while that of the latter is only

there are 10-6~10-4Ω · cm.
