Neodymium magnets, a category of rare earth magnets, are the strongest type of permanent magnet known to earth.  With the potential to store a high mount of magnetic energies and energy density, these magnets have become the first rare-earth application to become commercialized in the manufacturing and production industries.  While General Motors initially commercialized the neodymium magnet in 1982 as an alternative to other permanent magnets that were considered high in cost, it later became the solutions to companies in a number of different industries with new and cost conserving manufacturing techniques.  With new techniques, deterioration disadvantages were eliminated with nickel plating became the standard in neodymium production.
