Neodymium iron boron,
Iimagnethi zomhlaba ezinqabileyo luhlobo lwemagnethi enamandla esisigxina eyenziwe kwialloys yezinto ezinqabileyo zomhlaba ezifana neodymium, praseodymium, kunye nesamarium. Ezi ngxubevange zomelele ngendlela emangalisayo kwaye zibonelela ngoluhlu olubanzi lwezibonelelo ezinje ngokuqina kwemagnethi ephezulu, uzinzo, ukuxhathisa kwi-demagnetization, kunye nokuqina.
Iimagnethi zomhlaba ezinqabileyo ziqhele ukusetyenziswa kwiinkqubo ezahlukeneyo ezinje ngeenjini, iijenereyitha, iiinjini zomoya, kunye neehard drives zekhompyuter. Ngapha koko, bomelele kangangokuba banenzuzo ebalulekileyo ngaphezu kweemagnethi zemveli, ezibenza babe yintandokazi phakathi kweenjineli kunye nososayensi.
