The coercivity, magnetization and remanent magnetization of magnetic materials represent the significance
An overview of magnetic materials. Magnetic material is mainly composed of transition elements, iron, cobalt, nickel and their alloys, which can produce magnetism directly or indirectly
The magnetic material is morphologically. It includes powder material, liquid material, block material, film material and so on.Magnetic material is widely used in electroacoustic, telecommunication, electric meter, motor, memory element, microwave component and so on. Magnetic tapes for recording language, music, image information, magnetic storage devices for computers, vouchers for passenger travel, magnetic cards for fare settlement, etc.. [edit this paragraph] classification of magnetic materials, magnetic materials are mainly divided into two categories, one is a kind of soft magnetic, is hard;
From the application function, the magnetic material is divided into: soft magnetic material, permanent magnetic material, magnetic recording - moment magnetic material, spin magnetic material and so on. Soft magnetic materials, magnetic materials, magnetic recording materials in magnetic moment both metal material and ferrite material; and the rotating magnetic material and high-frequency soft magnetic materials is ferrite material, because the metal will produce large eddy current effect in high frequency and microwave frequency, resulting in metal magnetic material can not be used, and the resistivity of ferrite is very high, will effectively overcome this problem, widely used.
Magnetic material from the material and structure, is divided into "metal and alloy magnetic material" and "ferrite magnetic material" two categories, ferrite magnetic material is divided into polycrystalline structure and single crystal structure material.
