About Neodymium Magnets:
Neodymium magnets are one of rare earth permanent magnets. Neodymium magnets are also known as NdFeB magnets, or neo rare earth magnets. Since it's very strong, people also simply call it super strong magnets or super powerful magnets. The major elements of this magnet include neodymium (Nd), iron (Fe) and boron (B), or NdFeB.
