NdFeB is a rare-earth magnet made from an alloy of Neodymium, Iron and Boron to form the Nd2Fe14B tetragonal crystalline structure. Reed switch applications that require highest magnet strength in the smallest size can use NdFeB magnets.
It has been suggested that Bonded neo be merged into this article. (Discuss) Proposed since April 2023.
A neodymium magnet (also known as NdFeB, NIB or Neo magnet) is the most widely used type of rare-earth magnet. It is a permanent magnet made from an alloy of neodymium, iron, and boron to form the Nd2Fe14B tetragonal crystalline structure. Developed independently in 1984 by General Motors and Sumitomo Special Metals, neodymium magnets are the strongest type of permanent magnet available commercially.
NdFeB magnets can be classified as sintered or bonded, depending on the manufacturing process used. They have replaced other types of magnets in many applications in modern products that require strong permanent magnets, such as electric motors in cordless tools, hard disk drives and magnetic fasteners.
