Magnetic materials
One of the three basic functional materials
Soft magnetic materials
Steel, iron, soft ferrite, multi-ferromagnetic amorphous materials
Hard magnetic materials
Alnico (AI-Ni-Co), permanent ferrite, Samarium (Sm-Co), sintered NdFeB (Nd-Fe-B) permanent magnet materials, bonded NdFeB (Nd-Fe-B) materials
Very high magnetic performance
Very high demagnetization resistance
Can be processed into various shapes
Anisotropic material
Devices using sintered NdFeB magnets have good energy-saving effects
Devices using sintered NdFeB magnets can be miniaturized
IT sector
Voice coil motors (VCM) in hard drives, driving motors of optical heads in optical drives (DVD), vibration motors in mobile phones
Generators
Wind turbines
Motors
Drive motors of hybrid vehicles, variable frequency air conditioner drive motors, elevator traction machines, linear motors, high-end washing machine drive motors, servo motors in automatic equipment (welding robots), automotive EPS servo motors, electric bicycle motors
Sensors
Speed sensors (Hall sensors) and displacement sensors in cars
Medical industry
MRI machines
Others
Speakers, headphones, magnetic chucks, filters, bag clasps
Sintered NdFeB magnets can generate a strong attraction to steel, used in magnetic chucks, magnetic separators, bag clasps, etc.
A coil conducting an unstable current generates an electromagnetism effect, interacting with the magnetic field produced by the magnet to produce vibrations. Magnets are used as magnetic sources for speakers.
According to Faraday's law of electromagnetic induction, magnets are used as magnetic sources in generators, such as wind turbines and various inductive sensors.
According to the Ampere's force law on conductors in a magnetic field, magnets can be used as magnetic sources in various permanent magnet motors, such as various NdFeB motors.
Utilizing the quantum magnetic properties on an atomic scale, magnets are used as magnetic sources in MRI machines.
