It is well known that the magnet can be divided into & other;
A permanent magnet & throughout;
With & other;
The permanent magnet & throughout;
A permanent magnet can be a natural product, also called lodestone, can also be made by human.
The permanent magnets, magnetic only under certain conditions will start.
However, in practice, a magnet can be divided into five categories: ndfeb permanent magnet, permanent magnet ferrite, samarium cobalt magnet, alnico magnets, rubber magnetic.
So, what are the different types of magnet purposes?
Modern magnetic ndfeb permanent magnet is the most powerful permanent magnets, which is the most widely used.
Its mainly used in electroacoustic, permanent magnet motor, communications, automotive electronics, magnetic machinery, aerospace, computer, household appliances, medical equipment, office automation, toys, gift box, leather products, magnetic jewelry and other fields.
Permanent magnetic ferrite in meters, generators, a telephone, speakers, TV is used as a permanent magnet and microwave devices, also used for recorder, pickup, speakers, magnetic core, also used for various kinds of instrument used in radar, communication, navigation, remote sensing and other electronic devices.
Samarium cobalt magnet working temperature can be as high as 300 degrees, at the same time have corrosion resistance and oxidation resistance, the current has been widely used in the detector, generators, radar, instrument, and other precision technology.
Alnico magnet high temperature resistance, corrosion resistance.
Mainly used in motors, sensors, medical instruments, hand tools, loudspeakers and all kinds of instrument.
Rubber magnet are gay and straight, gay suction weaker is mainly used for propaganda,
Refrigerator, car stickers, etc. )
, decoration gifts, fridge magnet, toys, teaching materials, etc.
The opposite sex stronger magnetic force can be used for small motors, sensors, magnetic adsorption supplies such as WWW.
