Permanent Industrial Square Block Disc Neodymium Magnet
Product Description
Neodymium magnet, also known as NdFeB magnet, is a tetragonal crystal system formed by Neodymium, iron and boron (Nd2Fe14B).
Sintered NdFeB magnet is mainly composed with rare earth, if the magnet is not electroplated,it will rusted and corroded easily when the magnet is under moist air environment.
Every custom neodymium magnet has a north seeking and a south seeking face on opposite ends. The north face of one magnet will always be attracted towards the south face of another magnet.
Magnetic Grade
Powerful Neodymium magnets are all graded by the material they are made of. As a very general rule, the higher the grade (the number following the 'N'), the stronger the magnet. The highest grade of neodymium magnet currently available is N52. Any letter following the grade refers to the temperature rating of the magnet. If there are no letters following the grade, then the magnet is standard temperature neodymium. The temperature ratings are standard (no designation) - M - H - SH - UH - EH.
