Kiʻekiʻe NdFeB Magnet mai ka hikina
ʻO ka wehewehe pōkole:
hangzhou magnet mana NdFeB Magnet, smco magnet, rotor, hui magnet, hui halbach
Kiʻekiʻe NdFeB Magnet mai ka hikina
Ka mana pohihihi o ka Hikina,
i hoʻoili ʻia no nā kaukani makahiki, ʻōlelo ʻia e Confucius
Nā kānaka koʻikoʻi
manawa kūpono a me kahi kūpono
Ma nā palapala mai ka wā Spring a me ka Autumn a me ka Warring States Wā, nā waiwai hao omagnetsua hoʻopaʻa pinepine ʻia.No ka laʻana, ʻo ka "pōhaku magnetik e kiʻi i ka hao" ma ka "Lu Shi Chun Qiu" i kākau ʻia i ke kenekulia ʻekolu BC, a ʻo ka "pōhaku magneti e kāhea i ka nila" ma ka "Guiguzi" ʻaʻole mamao loa mai kekahi i kekahi.I kēia manawa, ʻike pinepine ʻia ka magnetism a hoʻohālikelike ʻia me ka hoihoi o ka makuahine aloha i kāna mau keiki.
Ua ʻōlelo ʻo Gao Yao o ka Eastern Han Dynasty i kāna hōʻike ʻana o "Lu Shi Chun Qiu": ʻO Stone ka makuahine o ka hao, akā aia nā pōhaku maikaʻi a maikaʻi ʻole.Hiki i ka pōhaku lokomaikaʻi ke hoʻohuli i kāna mau keiki (hao), akā ʻaʻole hiki i ka pōhaku maikaʻi ʻole ke huki iā ia..No laila, ma mua o ka Han Dynasty, ua kākau ʻia nā mea hoʻokalakupua e like me "Ci Shi", ʻo ia hoʻi "Pohaku o ke aloha".
Ma hope mai, hoʻohana mau ka poʻe i nā magnet e hoʻowalewale i nā metala ʻē aʻe a i ʻole nā mea.He aha ka hopena?
ʻO ka puke "Huainanzi" i kākau ʻia ma ka Western Han Dynasty i kākau: "Inā hiki i kahi pōhaku lokomaikaʻi ke hoʻohui i ka hao, e paʻakikī ke hoʻohana ʻia e alakaʻi i nā tile.""ʻAʻole hiki ke hoʻohui i ke keleawe."I ka wā o nā Aupuni ʻEkolu, ua ʻōlelo pū kekahi: "ʻAʻole hiki ke hoʻokuʻu ʻia ka pōhaku o ka lokomaikaʻi."ʻO nā mea i kapa ʻia ʻo "curved needles" pili paha i nā nila i hana ʻia me nā metala e like me ke gula, ke kālā, a me ke keleawe, ʻaʻole i huki ʻia e nā magnet.
Hōʻike kēia mau moʻolelo i ka ʻike ʻana o ka mōʻī Han e hiki ke huki wale i ka hao akā ʻaʻole nā mea ʻē aʻe.He wahi holomua kēia.Ua ʻike mākou hiki i nā magnet ke huki wale kekahi i kekahi i ka hao, akā inā pili nā magnet i kekahi i kekahi, ʻoi aku ka paʻakikī o ke kūlana.ʻElua mau kia mākēneki, kapa ʻia kekahi pole hema a kapa ʻia kekahi pole ʻākau.I kēlā manawa, aia kahin ʻO Luan Da ka mea alchemist i hana i ʻelua mau magnet, ua like ia me nā ʻāpana chess a kokoke i kekahi.Ua ʻōlelo ʻia ʻaʻole hiki iā lākou ke huki wale kekahi i kekahi ("hōʻole kekahi i kekahi"), akā "hoʻokuʻu kekahi i kekahi me ka pau ʻole", ʻo ia hoʻi, hoʻokuke kekahi i kekahi.ʻO kēia ka mea i kapa ʻia ʻo "fighting chess".Ua hana ʻo ia i kēia hana hoʻopunipuni iā Emperor Wu o ka mōʻī Han,aUa hauʻoli ka Emepera, no laila ua loaʻa iā ia ke kūlana kūhelu o "Five-profit General".
