Is iron a magnetic conductive material?
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.
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.
Magnetic materials mainly refers to the excessive iron, cobalt, nickel alloy can extremely directly or indirectly produce magnetic material. The magnetic material from the material and structure, divided into metal and alloy magnetic materials "and" ferrite magnetic materials "two categories, the ferrite magnetic material is divided into multiple the crystal structure and crystal structure of materials.
