N42 Magnet and N42SH Neodymium Magnets Demagnetization Curves

Sintered NdFeB Magnet Grades

Generally, the sintered NdFeB magnet grades are strings containing three parts, i.e. “N” + “number” + “letter”. The part “N” is the initial letter of neodymium, meaning it is a sintered neodymium iron boron magnet. So it is constant for all the neodymium magnet grades. The part “number” represents value of maximum energy product (BH)max (in CGS unit). The value varies from 28 to 52. The part “letter” reflects level of intrinsic coercivity Hcj. The levels include “M” (Hcj ≥… Read More
