Iimagnethi ze-NdFeB zenziwe ikakhulu nge-neodymium (Nd), intsimbi (Fe), kunye ne-boron (B).Zenziwa ngenkqubo ye-metallurgy engumgubo, apho imathiriyeli ekrwada iyanyibilika, igalelwe kwiingots, icunyuzwe ibe ngamasuntswana amancinane, emva koko icinezelwe kwimilo efunekayo.Iimagnethi ze-NdFeB zinoxinzelelo olukhulu lwamandla, okuthetha ukuba zinokugcina isixa esikhulu samandla kazibuthe kumthamo omncinci.Zikwabonisa iipropathi ezigqwesileyo zemagnethi, ezinje nge-coercivity ephezulu (ubuchule bokumelana ne-demagnetization), i-remanence ephezulu (amandla okugcina imagneti emva kokususwa kwemagnethi yangaphandle), kunye noxinaniso oluphezulu lwemagnethi (isixa semagnethi yendawo nganye ).
