ʻO nā māneta kīʻaha he mau māneta poepoe i manaʻo ʻia e hoʻohana ʻia i loko o kahi kahawai a kīʻaha paha.ʻIke ʻia he mau ʻāpana metala ʻano poepoe maʻamau, e like me ka mea i hōʻike ʻia ma ke kiʻi pili.ʻO nā kīʻaha kīʻaha, ʻoiaʻiʻo, hiki ke hana i kahi māla magnetic.Hiki iā ʻoe ke hoʻokomo iā lākou i loko o ke kahawai a i ʻole ke kīʻaha e paʻa ai ka mea.
Ua kapa ʻia lākou he "cup magnets" no ka mea hoʻohana pinepine ʻia lākou i loko o nā kīʻaha.Hiki ke hoʻohana ʻia ke kīʻaha magnet no ka hoʻopaʻa ʻana i ke kīʻaha metala a pēlā e pale ai i ka hāʻule ʻana.ʻO ka hoʻokomo ʻana i kahi kīʻaha magnet i loko o ke kīʻaha metala e paʻa ia.Hiki ke hoʻohana ʻia nā magnet kīʻaha no nā mea ʻē aʻe, akā ua pili pū lākou me nā kīʻaha.
ʻO nā kīʻaha kīʻaha, e like me nā ʻano magnet mau loa, i hana ʻia me nā mea ferromagnetic.ʻO ka hapa nui o lākou i hana ʻia me ka neodymium.ʻO ka Neodymium, me ka helu atomika 60, he metala honua laha ʻole ia e hoʻopuka ai i kahi kahua mākēneki ikaika loa.E hoʻopili ʻia nā magnet kīʻaha i loko o ke kahawai a i ʻole ke kīʻaha, e hoʻopaʻa i ka mea a pale i ka hāʻule ʻana.
He poepoe ka loko o nā ala a me nā kīʻaha, no laila, ʻaʻole kūpono ia no nā magnet square a i ʻole rectangular.Hiki ke hoʻokomo ʻia kahi magnet liʻiliʻi i loko o ke kahawai a i ʻole ke kīʻaha, akā ʻaʻole ia e paʻa me ka lalo.ʻO nā magnet kīʻaha hoʻokahi hopena.Hana ʻia lākou ma ke ʻano poepoe i kūpono i loko o ka hapa nui o nā kahawai a me nā kīʻaha.
Loaʻa kēia mau mea no nā kīʻaha kīʻaha:
- Samarium Cobalt (SmCo)
- Neodymium (NdFeB)
- AlNiCo
- Ferrite (FeB)
ʻO ka laulā o ka wela noi nui loa he 60 a 450 °C.
Nui nā ʻano hoʻolālā like ʻole no ka ipu hao a me nā electromagnets, e like me ka palahalaha, ka lāʻau wili, ka stud wili, ka lua countersunk, ma loko o ka lua, a me ka lua threaded.Loaʻa mau ka magnet e hana no kāu noi no ka mea he nui nā koho hiʻohiʻona ʻokoʻa.
ʻO kahi mea hana paʻa a me nā ʻili pole kīnā ʻole e hōʻoiaʻiʻo i ka ikaika paʻa magnetic maikaʻi loa.Ma lalo o nā kūlana kūpono, perpendicular, ma kahi ʻāpana kila 37 i hoʻopalahalaha ʻia i ka mānoanoa o 5 mm, me ka ʻole o ka ea, ua ana ʻia nā mana paʻa i kuhikuhi ʻia.ʻAʻohe ʻokoʻa o ka huki ʻana e nā hemahema liʻiliʻi o ka mea magnetic.
