Developed in 1982 by General Motors and Sumitomo Special Metals, neodymium magnets 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 Magnets, such as motors in cordless tools, hard disk drives and magnetic fasteners.
