ʻO nā mākēneki NdFeB ʻano apo, ʻike ʻia hoʻi he neodymium ring magnets, he ʻano o ka magnet mau loa e hōʻike ana i kahi puka i waenakonu o ke apo. Hana ʻia kēia mau magnet mai ka hui pū ʻana o ka neodymium, iron, a me boron, a ua ʻike ʻia no ko lākou mau waiwai magnetic ikaika a paʻa.
ʻO ka hoʻolālā ʻano apo o kēia mau mea hoʻokalakupua e kūpono iā lākou no ka hoʻohana ʻana i nā noiʻi ʻenehana a me nā noiʻi ʻepekema, e like me nā kaʻa, nā mea hana, nā leo kani, a me nā bearings magnetic. Hiki iā lākou ke hoʻohana ʻia i nā huahana mea kūʻai aku, e like me nā paʻi magnetic no nā ʻeke lima a me nā mea nani.
Hiki mai nā mākēneki NdFeB me ke apo i nā ʻano nui a me nā ikaika, mai nā mākēneki liʻiliʻi hiki ke hoʻopili ʻia ma kahi manamana lima a hiki i nā magnet nui he mau iniha ke anawaena. Hoʻohana ʻia ka ikaika o kēia mau magnet ma ke ʻano o ko lākou ikaika kahua magnetic, i hāʻawi pinepine ʻia i nā ʻāpana gauss a i ʻole tesla.
