Ndfeb materyèl mayetikse yon alyaj nan neyodim ak oksid fè, elatriye, ki rele tou mayetik asye. Kòm prensipal materyèl la anvan tout koreksyon nan fè ndfeb leman se trè bon mache, rezèv yo nan neyodim ra latè se 10 a 16 fwa pi plis pase samaryom, se konsa pri a tou relativman pi pi ba pase leman cobalt samaryom.

Ndfeb magnetic material is an alloy of neodymium and iron oxide, etc, also called magnetic steel. As the main raw material of iron ndfeb magnet is very cheap, the reserves of rare earth neodymium is 10 to 16 times more than samarium, so the price also relatively much lower than samarium cobalt magnet.
