what are neodymium magnets made of
A neodymium magnet (also known as NdFeB, NIB or Neo magnet), the most widely used type of rare-earth magnet, is a permanent magnet made from an alloy of neodymium, iron and boron to form the Nd 2 Fe 14 B tetragonal crystalline structure.ass production is planned for 2017. As of 2012, 50,000 tons of neodymium magnets are produced officially each year in China, and 80,000 tons in a company-by-company build-up done in 2013. China produces more than 95% of rare earth elements, and produces about 76% of the world's total rare-earth magnets.
