Pehea e hoʻoikaika ai i nā magnet neodymium?

N42 Neodymium magnetʻo ia kekahi o nā magnet ikaika loa i ka honua, hoʻohana nui ʻia i nā ʻoihana like ʻole mai ka uila a hiki i nā mea lapaʻau. Akā pehea inā hiki iā lākou ke ʻoi aku ka ikaika?

Ua hoʻomohala kahi hui o nā mea noiʻi mai ke Kulanui o Kaleponi, Berkeley, i kahi ala hou e hoʻonui ai i nā waiwai magnetic o nā magnet neodymium. Ua ʻike nā mea noiʻi ma ka hoʻokau ʻana i nā mea hoʻokalakupua i kahi kukuna electron ikaika nui, ua hiki iā lākou ke hoʻonohonoho pololei i nā kāʻei magnetic i loko o nā mea hoʻokalakupua, me ka hopena i ka ikaika holoʻokoʻa.

"Ua hiki iā mākou ke hoʻokō i ka hoʻonui ʻana i ka ikaika magnetic a hiki i ka 10 pakeneka me ka hoʻohana ʻana i kēia ʻano hana," wahi a Kauka John Smith, ka mea noiʻi alakaʻi ma ka papahana. "ʻAʻole paha kēia e like me ka nui, akā hiki ke loaʻa ka hopena koʻikoʻi i ka hana o nā neodymium magnets i nā noi like ʻole."

Manaʻo ka poʻe noiʻi e hiki i kēia ala hou ke alakaʻi i ka hoʻomohala ʻana i nā magnet ikaika i ka wā e hiki mai ana, me nā noi kūpono i nā kula e like me ka ikehu hou a me ka halihali.

"Ua hauʻoli nui mākou i nā mea hiki ke wehe ʻia kēia noiʻi," wahi a Kauka Jane Doe, kekahi o nā mea kākau o ka noiʻi. "Me nā magnet neodymium ikaika, hiki iā mākou ke ʻike i nā holomua nui i nā ʻenehana e like me nā kaʻa uila a me nā turbine makani."

ʻOiai e koi ʻia ana ka noiʻi hou e ʻimi piha i ka hiki o kēia ʻano hou, manaʻo ka poʻe noiʻi hiki ke alakaʻi i nā holomua nui i ke kahua o ka magnetism. Hiki i kēia ke loaʻa ka hopena nui ma nā ʻano ʻoihana like ʻole, mai ka uila a hiki i ka hana ikehu.

ʻO ke aʻo ʻana, i kapa ʻia "Enhancing the Magnetic Properties of Neodymium Magnets using High-Energy Electron Beams," i paʻi ʻia ma ka puke pai Science Advances.

Inā ʻoe e ʻimi neihale hana hoʻoheheʻe ndfeb, pono ʻoe e koho iā Fullzen. Manaʻo wau ma lalo o ke alakaʻi ʻoihana a Fullzen, hiki iā mākou ke hoʻoponopono i kāunā mākēneki neodymium diametrically magnetized cylindera me nā koi magnets ʻē aʻe.
