Are magnetic materials used much in daily life?

Answer:

Magnetic materials can be used for electro acoustic, telecommunications, electricity, motor, can also be used as a memory element, such as microwave components, can be used to record the language, music, image information, computer tape magnetic storage device, Passenger Fare settlement vouchers and magnetic card etc.. The above answer comes from the magnet industry in germany.

The rotary 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. 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 is widely used in electroacoustic, telecommunication, electric meter, motor, memory element, microwave component and so on.

Magnetic materials mainly refers to the excessive iron, cobalt, nickel and its alloy can directly or indirectly from the magnetic substance. Magnetic materials 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. 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 material, permanent magnetic material and magnetic recording - magnetic material have both metallic and ferrite materials;
