Features of NdFeB magnet :
Neodymium magnets are mainly made from neodymium ,iron, and boron. It is the ideal magnetic material in the world till now and have been used universally in the world . It has super strong magnetic force and high intrinsic coercive force and after concocting , it can stand very high working temperature, as high as 200 centigrade.
All These special features of NdFeN material make it irreplaceable in the world.
So till now, it has universally been used in electronics, aviation, motors, automobiles, medical apparatus,
transmission machine... and even in many details of our everyday life.
