Hiki mai nā mākēneki NIB i nā māka like ʻole, e pili ana i ka ikaika o kā lākou mau māla magnetic, mai ka N35 (nāwaliwali a me ka liʻiliʻi loa) a i ka N52 (ikaika, ʻoi aku ka pipiʻi a ʻoi aku ka brittle). He 50% ka ikaika o ka magnet N52 ma mua o ka magnet N35 (52/35 = 1.49). I ka US, he mea maʻamau ka loaʻa ʻana o nā mea hoʻohana i nā mea hoʻohana ma ka pae N40 a i ka N42. I ka hana nui, hoʻohana pinepine ʻia ka N35 inā ʻaʻole manaʻo nui ka nui a me ke kaumaha no ka mea ʻuʻuku ke kumukūʻai. Inā he mea koʻikoʻi ka nui a me ke kaumaha, hoʻohana mau ʻia nā māka kiʻekiʻe. Aia ke kumukūʻai ma ke kumu kūʻai o nā māka kiʻekiʻe loa no laila ʻoi aku ka maʻamau o ka ʻike ʻana i nā magnet N48 a me N50 i hoʻohana ʻia i ka hana ʻana me N52.
✧ Pehea e koho ʻia ai ka papa?
ʻO nā magnet Neodymium a i ʻole ka mea maʻamau i kapa ʻia ʻo NIB, NefeB a i ʻole super magnets ka mea ikaika loa a me ka hoʻohana nui ʻana i nā magnet pāʻoihana i loaʻa ma ka honua holoʻokoʻa. Me ka haku mele ʻana o Nd2Fe14B, loaʻa i nā neo magnets kahi ʻano crystalline tetragonal a ua hoʻokumu nui ʻia i nā mea o neodymium, Iron a me Boron. I loko o nā makahiki, ua hoʻololi maikaʻi ʻia ka neodymium magnet i nā ʻano mea like ʻole o nā magnet mau loa no ka hoʻohana ākea ʻana i nā kaʻa, nā uila a me nā mea hana like ʻole o ke ola. Ma muli o ka ʻokoʻa o ke koi o ka magnetism a me ka huki ikaika no kēlā me kēia hana, hiki ke loaʻa nā neodymium magnets i nā papa like ʻole. Hoʻopili ʻia nā magnet NIB e like me ka mea i hana ʻia ai lākou. Ma ke ʻano maʻamau, ʻoi aku ka kiʻekiʻe o nā māka, ʻoi aku ka ikaika o ka magnet.
Hoʻomaka mau ka inoa neodymium me ka 'N' a ukali ʻia e kahi helu helu ʻelua i loko o ka moʻo o 24 a hiki i 52. ʻO ka huapalapala 'N' ma nā māka o nā neo magnets ke kū nei no ka neodymium aʻo nā helu ma lalo e hōʻike ana i ka huahana ikehu kiʻekiʻe o ka kikoʻī. magnet i ana ʻia ma 'Mega Gauss Oersteds (MGOe). ʻO Mgoe ka hōʻailona kumu o ka ikaika o kēlā me kēia neo magnet a me ka laulā o ke kahua magnetic i hana ʻia e ia i loko o nā mea hana a noi paha. ʻOiai e hoʻomaka ana ka pae kumu me N24 akā naʻe, ʻaʻole i hana hou ʻia nā papa haʻahaʻa. Pēlā nō, ʻoiai ke manaʻo ʻia ka nui o ka ikehu huahana o NIB a hiki i ka N64 akā ʻaʻole i ʻimi ʻia nā pae ikehu kiʻekiʻe ma ke kālepa a ʻo N52 ka papa neo kiʻekiʻe loa i loaʻa i nā mea kūʻai.
ʻO nā leka ʻē aʻe ma hope o ka papa e pili ana i nā helu wela o ka magnet, a i ʻole ka nele o ia. ʻO nā helu wela maʻamau ʻo Nil-MH-SH-UH-EH. ʻO kēia mau leka hope e hōʻike ana i ka pae kiʻekiʻe e hana ana i ka wela ʻo ia hoʻi ka mahana Curie e hiki ai i kahi magnet ke kūpaʻa ma mua o ka nalowale mau ʻana o kāna magnetism. Ke hoʻohana ʻia kahi magnet ma mua o ka mahana Curie, ʻo ka hopena ka nalowale o ka huahana, hoʻemi ʻia ka huahana a me ka demagnetization hiki ʻole ke hoʻololi.
Eia nō naʻe, ʻo ka nui kino a me ke ʻano o kēlā me kēia neodymium magnet he mea koʻikoʻi hoʻi i kona hiki ke hana pono i nā wela kiʻekiʻe. Eia kekahi, ʻo kekahi mea e hoʻomanaʻo ai, ʻo ka ikaika o kahi magnet maikaʻi maikaʻi e like me ka helu, no laila ʻo N37 wale nō 9% nāwaliwali ma mua o N46. ʻO ke ala hilinaʻi loa e helu ai i ka helu pololei o kahi neo magnet ma o ka hoʻohana ʻana i kahi mīkini hoʻāʻo hysteresis graph.
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!
