About Neodymium Magnets: Neodymium Iron Boron (NdFeB) magnets are composed of Nd, Fe, B, Dy, Co and other minor elements. They have excellent magnetic property and are extremely strong for their small size. NdFeB magnets are permanent, and have a high maximum energy product. Over the last 10 years, due to high ratio of performance over price, the NdFeB
