Neodymium is used to make very strong magnets, which are key parts of magnetic levitation technology. Maglev trains use these magnets to float above the tracks, reducing friction and allowing for high-speed travel.
Neodymium is a rare-earth metal element that forms part of powerful permanent magnets when combined with iron and boron. These neodymium magnets are used in headphones, computer hard drives, and maglev systems because they create strong magnetic fields in a small size.
