Ua lilo ʻo Neodymium magnet i mea hoʻohana nui ʻia i ka ʻoihana hou, mahalo i ko lākou ikaika magnetic kiʻekiʻe a me ke kūʻē ʻana i ka demagnetization.Hiki ke loaʻa iā lākou ma nā noi like ʻole, mai nā cones leo a i nā mīkini MRI.ʻO kekahi o nā mea koʻikoʻi i ka hoʻoholo ʻana i ka hana o nā magnet neodymium ʻo kā lākou papa.Ma kēia ʻatikala, e kūkākūkā mākou pehea e koho ai i ka pae o nā magnet neodymium e kūpono i kāu mau pono.
ʻO ka mea mua, e kamaʻilio e pili ana i ke ʻano o ka "papa" i ka pōʻaiapili o nā magnet neodymium.ʻO ka waiho wale ʻana, pili ia i ka ikaika o ke kahua magnetic e hiki ai i ka magnet ke hana.Hāʻawi ʻia kēlā me kēia papa i kahi helu, ma ke ʻano maʻamau ʻo Nxx, kahi xx e hōʻike ana i ʻelua mau huahelu e hōʻike ana i ka huahana ikehu kiʻekiʻe o ka magnet ma mega gauss-oersteds (MGOe).ʻO ka huahana ikehu kahi ana o ka ikaika a me ka mānoanoa.
No laila, pehea ʻoe e hoʻoholo ai i ka pae o ka neodymium magnet ka mea maikaʻi loa no kāu noi?Eia kekahi mau mea e noʻonoʻo ai:
1. Nā koi noi: ʻO ka hana mua e ʻike i nā koi kikoʻī o kāu noi.He aha ka ikaika i makemake ʻia o ke kahua magnetic?He aha ka mahana a me nā kūlana kaiapuni e pono ai ka magnet e kū ai?He aha ka nui a me ke ʻano o ka magnet āu e pono ai?ʻO ka pane ʻana i kēia mau nīnau e kōkua iā ʻoe e hōʻemi i ka laulā o nā māka i kūpono i kāu mau pono.
2. Kumu kūʻai: He mea kūʻai nui nā mea magnet Neodymium i hoʻohālikelike ʻia me nā mea magnet ʻē aʻe, e like me nā magnet ceramic.ʻOi aku ke kumu kūʻai ʻoi aku ka nui o nā magnet kiʻekiʻe, no laila pono ʻoe e kaulike i nā koi hana o kāu noi me kāu kālā.
3. ʻO ka hana a me ka nui: ʻO ke kiʻekiʻe o ke kiʻekiʻe o ka magnet, ʻoi aku ka ikaika o ke kahua magnetic hiki iā ia ke hana.Eia nō naʻe, hiki ke palupalu a paʻakikī i ka mīkini a mālama ʻia nā magnet kiʻekiʻe.Inā makemake kāu noi i kahi magnet liʻiliʻi, a inā pono ʻoe e hoʻokomo i ka magnet i loko o kahi ākea, ʻoi aku ka maikaʻi o ka magnet haʻahaʻa.
4. Ke kū'ē i ka wela: He mea maʻalahi ka neodymium magnet i nā hoʻololi wela, a emi iho ka huahana ikehu o ka magnet i ka piʻiʻana o ka mahana.Hoʻolālā ʻia kekahi mau māka o nā magnet neodymium e kū i nā wela kiʻekiʻe ma mua o nā mea ʻē aʻe.Inā pili kāu palapala noi i nā kaiapuni wela kiʻekiʻe, pono ʻoe e koho i kahi māka e hiki ke mālama i kona ikaika magnetic ma lalo o ia mau kūlana.
5. Hoʻopiʻi: He mea maʻalahi nā neodymium magnet i ka corrosion a me ka oxidation, no laila ua uhi pinepine ʻia lākou me kahi papa pale o ka nickel a i ʻole nā metala ʻē aʻe.Pono paha kekahi mau māka o nā magnet neodymium i ka uhi ʻokoʻa a i ʻole ka mālama ʻana i luna e kūpono i kāu noi.
I ka hōʻuluʻulu manaʻo, pono e noʻonoʻo pono ke koho ʻana i ka pae kūpono o nā magnet neodymium i kāu mau koi noi, kālā, a me nā ʻano hana o ka magnet.Hiki i nā mea e like me ka nui, ka pale wela, a me ka uhi ʻana i nā mea āpau i ka hoʻoholo ʻana i ka papa i kūpono no kāu mau pono.Inā ʻoe e hoʻolālā ana i kahi huahana hou a hoʻomaikaʻi paha i kahi mea i loaʻa, ke koho ʻana i ka māka kūpono o ka neodymium magnet hiki ke hana i nā ʻokoʻa āpau i ka hoʻokō ʻana i ka hana āu e makemake ai.
