ferrite magnets are non-metallic magnetic material, which is composed of iron oxide and one or more other metal oxides (for example: nickel oxide, zinc oxide, manganese oxide, magnesium oxide, barium oxide, strontium oxide, etc.) preparation sintering. relative magnetic permeability which can be up to several thousand, the resistivity is 1011 times the metal, eddy current loss is small, suitable for the production of high frequency electromagnetic devices. ferrite magnets can divided into five category: hard magnets, soft magnets, magnetic moment, the spin magnets and pressure magnets.
     Soft magnetic materials are easy to demagnetization, such as zinc ferrite and chromium nickel zinc ferrite, etc. ferrite magnets are versatile, variety, quantity, value a high ferrite material which is mainly used for all kinds of inductance components such as filter core, transformer core, radio core, as well as audio and video tape heads, etc., are also key components of magnetic recording material
