Neodymium magnet
Videos
A neodymium magnet is a permanent magnet made from an alloy of neodymium, iron, and boron that forms the Nd2Fe14B tetragonal crystalline structure. They are the most widely used type of rare-earth mag

A rare-earth magnet is a strong permanent magnet made from alloys of rare-earth elements. Developed in the 1970s and 1980s, rare-earth magnets are the strongest type of permanent magnets made, produci
