Custom Super Strong Magnetic Force N52 Neodymium Round Hollow Cylinder Magnet
Sintered NdFeB magnets have high magnetic permeability and can provide a powerful magnetic field for manufacturing various electronic devices.
Neodymium magnets are classified according to the material they are made of. The higher the level (the number after "N"), the stronger the magnet. The highest grade neodymium magnet currently available is N52 The grade of commonly used neodymium magnets is N35, which is the most cost-effective brand. Any letter after the level refers to the temperature level of the magnet. If there is no letter after the grade, the magnet is standard temperature neodymium. The temperature rating is standard (not specified) - M – H – SH – UH – EH.
