ʻO ka ʻepekema ma hope o nā mākēneki neodymium: wehe i ko lākou mana

Neodymium magnetsʻike ʻia no ko lākou ikaika kupaianaha a hoʻohana ʻia i ka nui o nā noi mai ka uila a hiki i nā mea lapaʻau. Akā he aha ka mea e ikaika ai kēia mau magnet? No ka hoʻomaopopo ʻana i kēia, pono mākou e ʻimi i ka ʻepekema ma hope o nā neodymium magnets a e ʻimi i nā manaʻo e like me ka saturation magnetic, coercivity, a me nā domain magnetic.

ʻO kekahi o nā mea nui i ka hoʻomaikaʻi ʻana i ka ikaika o nā magnet neodymium ʻo kā lākou saturation magnetic kiʻekiʻe. ʻO ka saturation mākēneki ka wahi i hoʻopaneʻe ʻole ʻia ai kahi mea a ua hōʻea i kona kiʻekiʻe loa. Loaʻa i nā magnetization neodymium kiʻekiʻe ka saturation magnetization, e ʻae iā lākou e hana i nā māla magnetic ikaika.

ʻO Coercivity kekahi waiwai nui o nā magnet neodymium. Ana ia i ke kū'ē o kekahi mea i ka demagnetization. He kiʻekiʻe ka coercivity nā neodymium magnets, ʻo ia ka mea hiki iā lākou ke mālama i kā lākou magnetization i mua o kahi kahua magnetic waho, e hoʻolilo iā lākou i kūpaʻa a hilinaʻi.

ʻO ka ikaika o nā neodymium magnets mai ka hoʻonohonoho ʻana o kā lākou mau kikowaena magnetic. I loko o kēia mau mea magnet, ua hoʻonohonoho ʻia nā kāʻei magnetic i nā kuhikuhi kikoʻī, e hana ana i kahi māla ikaika holoʻokoʻa. Loaʻa kēia alignment ma o ke kaʻina hana i kapa ʻia ka magnetization, kahi e hoʻopili ʻia ai kahi māla magnetic waho i ka mea, e hoʻohālikelike ai i nā domain magnetic i ka ʻaoʻao like.

ʻO ka hui pū ʻana o ka saturation magnetic kiʻekiʻe, coercivity, a me nā kāʻei magnetic i hoʻonohonoho pono ʻia e ikaika loa nā magnet neodymium. ʻO kēia ikaika ka mea kūpono iā lākou no nā noi e koi ana i nā māla magnetic ikaika, e like me nā kaʻa uila, nā mīkini hoʻohālikelike magnetic (MRI), a me nā mea hoʻohui magnetic.

I ka hōʻuluʻulu ʻana, hiki ke hoʻohālikelike ʻia ka ikaika o nā magnet neodymium i ko lākou saturation magnetic kiʻekiʻe, ikaika hoʻoikaika, a me ka alignment domain magnetic. ʻO ka hoʻomaopopo ʻana i kēia mau loina ʻepekema e kōkua iā mākou e hoʻomaopopo i nā waiwai kupaianaha o nā neodymium magnets a me kā lākou ākea o nā noi i ka ʻenehana hou.

Ma Xiamen Eagle Electronics & Technology Co., Ltd., ua kūpaʻa mākou i ka hāʻawi ʻana i nā hopena magnetic kiʻekiʻe e hoʻokō i nā pono like ʻole o kā mākou mea kūʻai. Hōʻike kā mākou neodymium magnet i kā mākou kūpaʻa i ka hana hou a me ka maikaʻi i ka ʻenehana magnetic. E hoʻokaʻaʻike mai iā mākou i kēia lā e aʻo hou e pili ana i ke ʻano o kā mākou mau magnet e hoʻonui ai i kāu mau noi a hoʻonui i kāu ʻoihana.
