Neodymium magnet:

neodymium magnet (also known as NdFeB, NIB or Neo magnet), the most widely used type of rare earth magnet, is a permanent magnet made from an alloy of neodymium, iron and boron to form the Nd2Fe14B tetragonal crystalline structure. Developed in 1982 by General Motors and Sumitomo Special Metals, neodymium magnet are the strongest type of permanent magnet commercially available. They have replaced other types of magnets in the many applications in modern products that require strong permanent neodymium magnet.

Neodymium magnet Applications:

Neodymium magnet have replaced Alnico and ferrite magnets in many applications where strong permanent magnets are required, because their greater strength allows the use of smaller, lighter magnets. These applications include:
