He aha nā Neodymium Magnets

ʻIke ʻia hoʻi ma ke ʻano he neo magnet, ʻo ka neodymium magnet kahi ʻano o ka mea hoʻokalakupua honua i loko o ka neodymium, ka hao a me ka boron. ʻOiai he mau mea hoʻokalakupua honua ʻē aʻe - me ka samarium cobalt - ʻo ka neodymium ka mea maʻamau. Hoʻokumu lākou i kahi māla magnetic ikaika, e ʻae ana i kahi pae kiʻekiʻe o ka hana. ʻOiai inā ua lohe ʻoe i nā magnet neodymium, akā naʻe, aia kekahi mau mea āu i ʻike ʻole ai e pili ana i kēia mau mea hoʻokalakupua honua.

✧ Hōʻikeʻike o nā Neodymium Magnets

Ua kapa ʻia ʻo ia ka mākēneki ikaika loa o ka honua, ʻo nā neodymium magnet he mau magnet i hana ʻia me ka neodymium. No ka hoʻokomo ʻana i ko lākou ikaika i ke kuanaʻike, hiki iā lākou ke hana i nā māla magnetic a hiki i ka 1.4 teslas. ʻO ka Neodymium, ʻoiaʻiʻo, he mea laha ʻole ka honua e hōʻike ana i ka helu atomika 60. Ua ʻike ʻia ia i ka makahiki 1885 e ka mea hoʻokalakupua ʻo Carl Auer von Welsbach. Me kēlā ʻōlelo, ʻaʻole i kokoke i hoʻokahi haneli ma hope a hiki i ka hana ʻana o nā neodymium magnets.

ʻO ka ikaika like ʻole o nā neodymium magnets e hoʻolilo iā lākou i koho maikaʻi loa no nā noi pāʻoihana like ʻole, aia kekahi o kēia mau mea:

ㆍPaʻa disk drive (HDDs) no nā kamepiula

ㆍPaʻa puka

ㆍ Nā ʻenekini kaʻa uila

ㆍ Nā mea hana uila

ㆍNā leo

ㆍ nā mea hana mana ʻole

ㆍKa hookele mana

ㆍNā ʻōlelo a me nā headphone

ㆍ Nā mea hoʻokaʻawale kūʻai

>> E kūʻai aku i kā mākou neodymium magnet ma aneʻi

✧ Ka Moʻolelo o nā Neodymium Magnets

Ua hana ʻia nā magnet Neodymium i nā makahiki 1980 mua e General Motors a me Sumitomo Special Metals. Ua ʻike nā hui ma ka hoʻohui ʻana i ka neodymium me ka liʻiliʻi o ka hao a me ka boron, hiki iā lākou ke hana i kahi magnet ikaika. Ua hoʻokuʻu ʻo General Motors a me Sumitomo Special Metals i nā neodymium magnets mua loa o ka honua, e hāʻawi ana i kahi koho ʻoi aku ka maikaʻi i nā mea hoʻokalakupua honua ʻē aʻe ma ka mākeke.

✧ Neodymium VS Mākēneki Ceramic

Pehea e hoʻohālikelike ai nā magnet neodymium me nā magnet seramika? ʻAʻole ʻoi aku ka maikaʻi o nā magnet keramika, e hoʻolilo iā lākou i koho kaulana no nā noi mea kūʻai aku. No nā noi pāʻoihana, akā naʻe, ʻaʻohe mea hoʻololi no nā magnet neodymium. E like me ka mea i haʻi mua ʻia, hiki i nā neodymium magnet ke hana i nā māla magnetic a hiki i ka 1.4 teslas. I ka hoʻohālikelike ʻana, hana maʻamau nā magnet seramika i nā māla magnetic me ka 0.5 a i ka 1 teslas wale nō.

ʻAʻole wale ʻoi aku ka ikaika o nā magnet neodymium, magnetically, ma mua o nā magnet seramika; ʻoi aku ka paʻakikī. He palupalu nā magnet seramika, hiki iā lākou ke hoʻopōʻino. Inā hoʻokuʻu ʻoe i kahi magnet seramika ma ka honua, hiki ke haki. ʻO nā magnet Neodymium, ma kekahi ʻaoʻao, ʻoi aku ka paʻakikī o ke kino, no laila ʻoi aku ka liʻiliʻi o ka haki ʻana i ka wā e hāʻule ai a i ʻole i ʻike ʻia i ke kaumaha.

Ma ka ʻaoʻao ʻē aʻe, ʻoi aku ka kūpaʻa o nā magnet seramika i ka corrosion ma mua o nā magnet neodymium. ʻOiai ke ʻike ʻia i ka haʻahaʻa ma ke ʻano maʻamau, ʻaʻole e ʻino a ʻōpala paha nā magnet seramika.

✧ Mea Hoʻolako Mākēneki Neodymium

ʻO AH Magnet kahi mea hoʻolako mea hoʻolale honua ʻokoʻa i ka noiʻi ʻana, hoʻomohala, hana a me ka hoʻokuʻu ʻana i nā kiʻekiʻe neodymium iron boron magnets, 47 mau māka o nā neodymium maʻamau, mai N33 a 35AH, a me GBD Series mai 48SH a 45AH loaʻa. Inā makemake ʻoe i kā mākou huahana, e ʻoluʻolu e kelepona mai iā mākou i kēia manawa!
