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. As its magnetic strength is very strong, people also simply call it super strong magnets or super powerful magnets. The main elements of this magnet include neodymium (Nd), iron (Fe) and boron (B).
