Sintered NdFeB permanent magnets can be divided into seven series according to the different intrinsic coercivity HcJ: N, M, H, SH, UH, EH and AH(TH), and each series is subdivided according to the magnitude of the magnet remanence Br and the maximum magnetic energy product BH (max).<\/p>

\u25aa The number represents the maximum energy product (BH) max of the product, and the higher the number, the larger the maximum energy product<\/p>

\u25aa The letters represent the classification of intrinsic coercivity, and the later the series, the greater the intrinsic coercivity<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
