Neodymium Magnets (Nd2Fe14B) are the strongest permanent magnets. A neodymium magnet can lift a thousand times its own weight. However, Neodymium-based magnets lose their magnetism at high temperatures and tend to rust. Neodymium magnets are used in products such as cellphones, louspeakers, headphones, computer hard disks. Due to this high magnetic capacity per weight, neodymium is used in the all kinds of electric motors, such as hybrid and electric automobiles, and in the electricity generators of some designs of commercial wind turbines.
