3. NdFeB magnets, ʻike ʻia hoʻi he neodymium magnets a i ʻole NdFeB magnets, he mau kristal tetragonal i hana ʻia me ka neodymium, ka hao, a me ka boron.E like me nāʻano hana likeʻole, hiki ke hoʻokaʻawaleʻia ka NdFeB mau mea paʻa i nā NdFeB i hoʻopaʻaʻia, NdFeB i hoʻopaʻaʻia, NdFeB wela, a me nā mea'ē aʻe.I kēia mau makahiki i hala iho nei, ua hoʻohana nui ʻia lākou i nā kaʻa ikehu hou, nā mea kūʻai uila, nuklea magnetic resonance imaging, makani mana hana, aerospace a me nā kula ʻē aʻe.ʻO NdFeB mau mea paʻa paʻa ʻo ia ke kolu o ka hanauna o ka honua paʻa mau mea me ka wikiwiki o ka hoʻomohala ʻana, ka noi ākea, ka hana kiʻekiʻe loa a me ka hana piha maikaʻi loa.

4.ʻO NdFeB magnet kahi mea manaʻo ikaika me ka huahana ikehu kiʻekiʻe, ikaika hoʻoikaika kiʻekiʻe, kūpaʻa kiʻekiʻe a pēlā aku.No laila, loaʻa iā ia kahi ākea o nā kahua noi i ka ʻoihana hou.

ʻO ka mea mua, hoʻohana nui ʻia nā magnet NdFeB i nā mea uila like ʻole e like me nā kaʻa, nā mea hana a me nā mea ʻike.No ka laʻana, hiki ke hoʻohana ʻia i loko o nā kaʻa o nā kaʻa uila, no ka mea hiki i nā magnets NdFeB ke hāʻawi i kahi kahua magnetic ikaika, a laila e hoʻomaikaʻi ai i ka pono a me ka hana o nā kaʻa uila.

ʻO ka lua, hoʻohana nui ʻia nā magnet NdFeB i nā huahana uila mea kūʻai aku e like me ka lolouila paʻakikī, nā mea pāʻani DVD a me nā stereos.Pono nā disk drives i nā poʻo e heluhelu i ka ʻikepili, a pono nā poʻo i nā mea magnetic e hoʻokō ai, no laila hiki ke hoʻohana ʻia nā magnet NdFeB i nā disk drive.Eia kekahi, hiki ke hoʻohana ʻia nā magnet NdFeB i nā mea haʻiʻōlelo i ka leo, hiki ke hoʻonui i ka mana puka a me ka maikaʻi o nā mea ʻōlelo.

Eia kekahi, hiki ke hoʻohana ʻia nā magnet NdFeB i nā mea lapaʻau a me nā mea hoʻokaʻawale magnetic a me nā māla ʻē aʻe.No ka laʻana, i ka lāʻau lapaʻau, hiki ke hoʻohana ʻia i nā mea hana hoʻonaninani magnetic (MRI), no ka mea hiki i nā neodymium iron boron magnets ke hāʻawi i ka nui o ke kahua magnetic e nānā i nā ʻiʻo a me nā ʻāpana i loko o ke kino kanaka.Ma ke kahua o nā mea hoʻokaʻawale magnetic, hiki ke hoʻohana ʻia nā magnet NdFeB i nā mea hoʻokaʻawale magnetic e kōkua i ka hoʻokaʻawale ʻana i nā mea like ʻole.

I ka pōkole, ua lilo nā mea magnet NdFeB i mea waiwai nui i ka ʻoihana hou ma muli o kā lākou mau waiwai magnetic maikaʻi loa.Hoʻohana nui ʻia ia i nā lako mana, nā mea hoʻohana uila, nā mea lapaʻau, a me nā mea hoʻokaʻawale magnetic, e lawe mai ana i ka ʻoluʻolu nui i ko mākou ola a me kā mākou hana.
