NdFeB magnet, he mau mea magnet honua laha ole i hoohana nui ia ma na ano hana a me na mea kalepa ma muli o ko lakou mau waiwai magnetic.Ua ʻike ʻia kēia mau magnet no ko lākou ikaika kiʻekiʻe, kūʻē i ka demagnetization, a me nā kumu kūʻai haʻahaʻa, e hana ana iā lākou i koho kaulana no nā ʻano mea uila, nā mea lapaʻau, a me nā mīkini.
ʻO ke ʻano oNdFeB magnetpaʻakikī loa, akā ʻo kēia paʻakikī e hāʻawi iā lākou i kā lākou mau waiwai kūʻokoʻa.Hana ʻia kēia mau magnet mai ka hui pū ʻana o ka neodymium, ka hao, a me ka boron, me nā mea liʻiliʻi o nā mea ʻē aʻe i hoʻohui ʻia e hoʻomaikaʻi i ko lākou mau waiwai magnetic.ʻO ke kī i kona ikaika ʻoi loa o ke kahua magnetic aia ma ka hoʻonohonoho ʻana o nā mana i loko o ke ʻano aniani o ka mea.
ʻO ka hana aniani oNdFeB magnetHe lattice tetragonal kahi i hoʻokumu ʻia ai nā ʻātoma neodymium a me boron i nā papa i loko o ka hoʻolālā lattice a noho nā ʻātoma hao i nā hakahaka ma waena o kēia mau papa.Hoʻopili kēia hoʻonohonoho kūʻokoʻa o nā mana i nā manawa magnetic o nā atoms, e hana ana i kahi māla ikaika.
Ma waho aʻe o kā lākou hoʻolālā aniani kū hoʻokahi,NdFeB magnethana pinepine ʻia i nā ʻano like ʻole a me nā nui, me nā lau, nā disks, a me nā poloka, e kūpono i nā noi like ʻole.I ke ʻano wae,Māhele Ndfeb magnethoʻohana nui ʻia i ka hana ʻana o nā kaʻa, nā mea hana, nā mea hoʻokaʻawale magnetic a me nā mīkini resonance imaging (MRI) ma muli o ko lākou ikaika kiʻekiʻe a me ka paʻa.
I ka hōʻuluʻulu ʻana, ʻo ke ʻano o nā magnet NdFeB kahi kumu nui i kā lākou waiwai magnetic maikaʻi loa.ʻO ka lattice tetragonal, i hui pū ʻia me ka hoʻonohonoho pololei ʻana o nā neodymium, hao a boron atoms, hiki i kēia mau magnet ke hōʻike i ka ikaika magnetic kiʻekiʻe a me ke kūʻē ʻana i ka demagnetization. Māhele Ndfeb magnet, ma keʻano, he mea waiwai nui i nāʻanoʻoihanaʻoihana a me nāʻoihana kālepa e koi ana i nā māla magnetic ikaika a paʻa.
