Sintered neodymium iron boron permanent magnets can be divided into seven series according to the different intrinsic coercivity HcJ: N (low coercivity), M (medium coercivity), H (high coercivity), SH (super high coercivity), UH (ultra high coercivity), EH (extremely high coercivity), and AH (abnormally high coercivity).
