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).
Applications of Arc Permanent Neodymium Magneten for Elevator MotorsNeodymium 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).
Sintered neodymium iron boron rare earth magnets are the most powerful permanent magnets, they are widely used in many industrial applications,such as all kinds of electromotors, separators, audio systems, wind turbine, sensors,medical equipment, toys, computers, elevators, cellphones, VCDs and maglev.
