Neodymium Iron Boron, NdFeB, magnets are the strongest magnets available.

Like Samarium Cobalt, NdFeB is termed a Rare Earth magnet. The Neodymium Iron Boron, NdFeB, magnets are made of an alloy primarily consisting of Neodymium, Iron and Boron and the alloy is chemically written as Nd2Fe14B. Although Neodymium Iron Boron is often written as NdFeB or Neodymium, it is often given the nickname of "Neo" and, very infrequently, "NIB".
