Neodymium (Neodymium & nbsp;magnet), Also known as neodymium iron boron magnet, is a collective term for powerful magnets whose chemical formula is Nd2Fe14B, a man-made permanent magnet that has so far been the most powerful permanent magnet.Its BHmax value is 5-12 times that of ferrite magnets, 3-10 times that of AlNiCo magnets; its coercive force is equivalent to 5-10 times that of ferrite magnets, 5- 15 times its potential high magnetic properties, can absorb the weight equivalent to 640 times its own weight. As the main raw material of NdFeB magnet iron is very cheap, the storage of rare earth neodymium 10-16 times more than samarium, so the price is much lower than the SmCo magnet.
