What is a magnetic material?
The magnetic material mainly refers to the material that can be directly or indirectly produced by excessive elements such as iron, cobalt, nickel, and alloys.
What are the classification of magnetic materials?
Magnetic materials are classified into two categories, "metal and alloy magnetic materials" and "ferrite magnetic materials", in terms of material and structure. Ferrite magnetic materials are divided into polycrystalline structures and monocrystalline structures.
What are the uses of magnetic materials?
In terms of application functions, magnetic materials are classified into: soft magnetic materials, permanent magnet materials, magnetic recording-magnetomagnetic materials, gyromagnetic materials, and the like. Soft magnetic materials, permanent magnetic materials, magnetic recording-magnetomagnetic materials include both metallic materials and ferrite materials; gyromagnetic materials and high-frequency soft magnetic materials can only be ferrite materials because metals are Frequency and microwave frequency will produce a huge eddy current effect, resulting in the use of metal magnetic materials can not be used, and the ferrite is very high resistivity, it will effectively overcome this problem, has been widely used.
What are the forms of magnetic material?
Magnetic materials are morphologically speaking. Including powder materials, liquid materials, bulk materials, thin film materials.
The wide application of magnetic materials: Magnetic materials are widely used, can be used in electro-acoustic, telecommunications, electric meters, motors, but also for memory components, microwave components. It can be used to record tapes for language, music, and image information, magnetic storage devices for computers, voucher for passengers' travel, and magnetic cards for fare settlement.
The important physical property of magnets is conduction. Nickel is a good material for magnetic conduction!
