NdFeB magnet are used in radar technology, satellite communications, remote control telemetry technology, electronic tracking, and electronic countermeasures technology. Magnets are used in magnetron tubes, magnetron traveling wave tubes, cathode ray tubes, circulators, etc.

Application in electrical engineering:

More than one-third of the output of rare earth permanent magnet materials is used to manufacture various permanent magnet motors. The advantages of permanent magnet motors are copper saving, power saving, light weight, small size and high specific power. Electric bicycle motors, computer drive motors, lathes, etc. are used to measure the speed and rotation speed of motors, elevator traction motors, mahjong motors, refrigerator air-conditioning motors, wind power motors, automobile motors, etc. The application fields are extremely wide.

Application in electroacoustic devices:

Such as speakers (speakers), microphones, hearing aids, stereo headphones (MP3, MP4), telephone receivers and electro-acoustic sensors, etc.

Application in magnetic mechanical engineering:

Magnetic machinery includes magnetic actuators, magnetic gears, magnetic brakes, magnetic clamps, magnetic fishing devices, magnetic bearings, magnetic pumps, magnetic valves, magnetic sealing doors, magnetic locks and permanent magnet jacks, permanent magnet conveyors, etc.
