What is NdFeB magnets?
NdFeB is a rare earth permanent magnet material composed of neodymium, iron and boron. Compared with other magnetic materials, it has outstanding magnetic performance advantages, such as high remanence (Br), high coercive force (Hcj), and high magnetic energy product (BHmax). The magnetic energy product (BHmax) of this magnet is greater than that of samarium cobalt magnet, and it was the material with the largest magnetic energy product in the world at that time.
