What is NdFeB magnets

Neodymium iron boron (NdFeB) is a quadrilateral crystal composed mainly of neodymium, iron, and boron (Nd2Fe14B).

It has high remanence (BR), high coercivity (Hcj) and high magnetic energy generation. It is the strongest permanent magnet ever made and the most commonly used rare earth magnet. The energy product of ndfeb magnets is between 28mGOe and 58MGOe.

Neodymium iron boron magnets are widely used in electronic products such as hard disks, mobile phones, headphones and battery-powered tools.

In order to avoid corrosion damage, it is necessary to do protective treatment on the surface of permanent magnet materials, such as electroplating with gold, nickel, zinc, tin, and coating the surface with epoxy resin.
