Permanent Neodymium Hidden Round Button Magnets 23 X 3mm PVC Coated
Neodymium (NdFeB) permanent magnet is composed of neodymium, iron, boron and a few transition metals. It has many advantages like high coercive force, high energy, high performance/ cost ratio and can be easily formed into various shapes and widely used in many fields such as aviation, electronics, instruments, meters, DC motors, Liner motors, MRI, medical and health products. It is the third generation of rare earth permanent magnet and at the same time the most powerful and advanced commercialized permanent magnet today.
Permanent NdFeB Neodymium magnets widely application:
1: Electro-acoustic: loudspeaker, headphone, earphone, stage sound device, alarm, microphone
2: Electric products: permanent magnetic actuator, vacuum circuit breaker, magnetic relay, watt-hour meter, water meter, sensor, reed switch
3: Motor areas: VCM, DVD-ROM, generator, electromotor, DC motor, linear motor
4: Mechanical equipment: magnetic separator, magnetic holder
5: Health care: nuclear magnetic resonance spectrometer, medical apparatus and instruments
