Neodymium Iron boron rare earth permanent magnet, as the third generation of rare earth materials, are widely used in motor, automotive, wind energy, electro-acoustic, communications, VCM, aerospace, nuclear magnetic resonance, magnetic components and other fields because of its super magnetic properties and good cost performance . Ferrite magnet is one of the most widely used magnets at present.It is widely used in DC motor, rotary motor, automobile motor (wiper, automobile starter, fuel pump, seat motor, etc.), magnetic separator, speaker, earphone, microwave oven and other fields due to its low cost.
There are many parts of the motor that use magnets, so there are also many kinds of magnets involved, such as rare-earth NdFeB magnet, Ferrite magnet, Samarium Cobalt permanent magnet, rubber magnet, all these materials will be used, as well as magnetic components combined by these magnet materials. Applications include VCM, CDDVD-ROM, generators, motors, servo motors, micro-motors, vibration motors and so on.
About 15% of rare earth magnets used in electro-acoustic fields are used to make electro-acoustic devices. For example: Speaker, microphone, pickup, stage sound, car audio, hearing aid, stereo headphones, telephone receivers and electro-acoustic sensors.The principle of electro-acoustic devices is basically the same, that is，when the current passes through the sound in the air gap, it will vibrate under the action of the magnetic field of the air gap, and cause the paper plate to vibrate to emit sound.
Magnets are necessary for many mechanical equipment, such as: magnetic separator, magnetic hoist, magnetic manipulator, magnetic latching relays, sensors, etc.Without magnetic materials, electrification would be impossible.
Many packaging industries are inseparable from the magnet, such as: bags magnet, leather magnet, magnetic toys, craft gift packaging, cosmetics packaging and so on.
In addition to the above industries,magnets are also widely used in industries such as electronics, electrical appliances, medical care and so on,specific products include: permanent magnetic vacuum circuit breaker ,magnetic latching relay, watt-hour meter, water meter, counter, dry reed pipe, sensor, nuclear magnetic resonance instrument, medical instrument, magnetic health care device, magnetized fuel economizer, magnetized paraffin inhibitor, pipeline descaler, magnetic fixture, automatic mahjong machine, magnetic lock, doors and windows magnet, etc.
