Neodymium Magnets (Neodymium Iron Boron Magnets), also known as NdFeB or Neo
magnets, are the most widely-used type of rare earth magnet. It is the strongest
type of permanent magnet made from an alloy of Neodymium, Iron, and Boron with the
Nd2Fe14B tetragonal crystalline structure. It has replaced other types of magnets
in many applications in modern products that require strong permanent magnets, such
as motors in cordless tools, hard disk drives, and magnetic fasteners.
