Hoʻokumu ʻia nā mākēneki NdFeB me neodymium (Nd), hao (Fe), a me boron (B).Hana ʻia lākou ma o ke kaʻina hana pauka, kahi e hoʻoheheʻe ʻia ai nā mea maka, hoʻolei ʻia i loko o nā ingots, ʻoki ʻia i loko o nā ʻāpana liʻiliʻi, a laila kaomi ʻia i ke ʻano i makemake ʻia.Loaʻa i nā magnet NdFeB ka ikehu kiʻekiʻe, ʻo ia hoʻi, hiki iā lākou ke mālama i ka nui o ka ikehu magnetic i kahi leo liʻiliʻi.Hōʻike pū lākou i nā waiwai magnetic maikaʻi loa, e like me ka coercivity kiʻekiʻe (ka hiki ke pale aku i ka demagnetization), remanence kiʻekiʻe (ka hiki ke mālama i ka magnetization ma hope o ka wehe ʻia ʻana o ke kahua magnetic waho), a me ke kiʻekiʻe magnetic flux kiʻekiʻe (ka nui o ka flux magnetic ma kēlā me kēia wahi. ).
