Applications of magnetic materials
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.
The magnetic material is morphologically. It includes powder material, liquid material, block material, film material and so on.The magnetic material application is very wide, from the compass, Horn / headset / microphone, antenna bar, household appliances (electric cooker), transformer, permanent magnet motor until the shuttle can find examples of magnetic materials.
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.. 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.
