About Neodymium Magnets:
Neodymium magnets are one of rare earthpermanent magnets. Neodymium magnets are also known as NdFeB magnets, or neorare earth magnets. As its magnetic strength is very strong, people also simplycall it super strong magnets or super powerful magnets. The main elements ofthis magnet include neodymium (Nd), iron (Fe) and boron (B).
