Ndfeb materyèl mayetik, kòm rezilta nan dènye nan devlopman nan materyèl ki ra latè pèmanan, paske nan mayetik ekselan li yo, ke yo rekonèt kòm "mayetik wa". BHmax valè li yo 5-12 fwa nan leman yo Ferit, 3-10 fwa nan leman alnico; Fòs coercive ekivalan li a senk a dis fwa nan menm gwosè a nan leman ferrite, 5-15 fwa nan leman alnico, potansyèl segondè mayetik li yo, ka souse moute ekivalan a nan yon pwa nan 640 fwa pwa pwòp li yo.

Ndfeb magnetic material, as the latest result of the development of rare earth permanent magnet materials, because of their excellent magnetic, known as "magnetic king". Its BHmax value 5-12 times of the ferrite magnets, 3-10 times of alnico magnets; Its coercive force equivalent to five to ten times of the same the size of ferrite magnets, 5-15 times of alnico magnets, its high magnetic potential, can suck up the equivalent of a weight of 640 times its own weight.
