Sintered Rare Earth magnets/Neodymium Magnets made from rare earth elements are the most powerful permanent magnetic materials commercially available.

Sintered rare earth magnets are manufactured by a powder metallurgical process which involves the sintering of powder compacts under vacuum. Magnets may be produced in large blocks for subsequent processing, or as tailor made components made by die pressing. Coatings may be applied depending on the expected environment. Block magnets, ring magnets, cylinder magnets, tile-shape magnets etc are available
