ʻO ka wehe ʻana i nā ʻokoʻa koʻikoʻi ma waena o nā Neodymium Magnets a me Electromagnets

He kuleana koʻikoʻi nā Magnets ma nā ʻano ʻano like ʻole, mai ka ʻenehana a hiki i ka lāʻau lapaʻau, e hoʻomaʻamaʻa i nā noi he nui. ʻElua mau ʻano magnetika maʻamauneodymium magnetsa me nā electromagnets, kēlā me kēia me nā hiʻohiʻona a me nā hana ʻokoʻa. E ʻimi kākou i nā ʻokoʻa koʻikoʻi ma waena o nā neodymium magnets a me nā electromagnets e hoʻomaopopo i kā lākou mau waiwai a me nā noi.

1. Huina:

ʻO nā magnet neodymium he mau magnet mau loa i hana ʻia mai kahi huila o neodymium, hao, a me boron (NdFeB). Kaulana kēia mau magnet no ko lākou ikaika ʻokoʻa a ʻo ia kekahi o nā magnet paʻa ikaika loa i loaʻa i ke kālepa. ʻO ka ʻokoʻa, ʻo nā electromagnets nā mea hoʻokalakupua pōkole i hana ʻia e ka hoʻokuʻu ʻana i kahi au uila ma o kahi wili uea i ʻeha a puni kahi mea kumu, maʻamau ka hao a i ʻole ke kila.

2. Mākēneki:

Hoʻopili ʻia nā magnet Neodymium i ka wā o ka hana ʻana a mālama mau i kā lākou magnetism. Ma hope o ka magnetized, hōʻike lākou i kahi māla magnetic ikaika me ka ʻole o kahi kumu mana waho. ʻO nā electromagnets, ma ka ʻaoʻao ʻē aʻe, koi ʻia i kahi au uila e hoʻohua ai i kahi māla magnetic. Ke holo nei ke au i ka wili uea, hoʻoulu ia i ka magnetism i loko o ka mea kumu, e hana ana i kahi māla magnetic. Hiki ke hoʻololi ʻia ka ikaika o ke kahua magnetic o ka electromagnet ma o ka hoʻololi ʻana i ke ʻano o kēia manawa e hele ana ma ka coil.

3. Ka ikaika:

Kaulana ʻia nā magnet Neodymium no ko lākou ikaika ʻokoʻa, ʻoi aku ka nui o nā ʻano magnet ʻē aʻe e pili ana i ka ikaika o ke kahua magnetic. Hiki iā lākou ke hoʻoikaika i nā mana ikaika a hoʻohana nui ʻia i nā noi e koi ana i ka ikaika magnetic kiʻekiʻe, e like me nā mīkini uila, nā mea ʻōlelo, a me nā mīkini hoʻohālikelike magnetic (MRI). ʻOiai hiki i nā electromagnets ke hana i nā māla magnetic ikaika, hilinaʻi ko lākou ikaika i ke kahe o kēia manawa ma ka coil a me nā waiwai o ka mea kumu. No laila, hiki ke hoʻolālā ʻia nā electromagnets e hōʻike i nā pae like ʻole o ka ikaika magnetic, e hoʻolilo iā lākou i mea maʻalahi no nā noi like ʻole.

4. Hoʻololi a me ka Mana:

ʻO kekahi o nā pōmaikaʻi nui o nā electromagnets ko lākou maʻalahi a me ka hoʻokele. Ma ka hoʻoponopono ʻana i ke ʻano uila e kahe ana i loko o ka coil, hiki ke maʻalahi ka ikaika o ke kahua magnetic o kahi electromagnet i ka manawa maoli. Hiki i kēia hiʻohiʻona ke hoʻohana i nā electromagnets i nā noi kahi e koi ʻia ai ka mana pololei ma luna o ke kahua magnetic, e like me ka automation ʻoihana, nā ʻōnaehana levitation magnetic, a me nā mea hana electromagnetic. ʻO nā magnet neodymium, ʻo ia nā magnet mau loa, ʻaʻole hāʻawi i ka pae like o ka maʻalahi a me ka mana ma luna o kā lākou mau waiwai magnetic.

5. Nā noi:

Loaʻa nā mea hoʻohana Neodymium magnetsma nā ʻano ʻano like ʻole, me ka uila, aerospace, a me nā mea lapaʻau, kahi e pono ai ko lākou kiʻekiʻe ikaika-a-nui. Hoʻohana ʻia lākou i loko o nā disk drive paʻakikī, nā headphone, nā pani magnetic, a me nā sensor, ma waena o nā noi ʻē aʻe. Hoʻohana ʻia nā Electromagnets i nā ʻano hana like ʻole, mai ka hana ʻana a me ka lawe ʻana i ka noiʻi ʻepekema a me ka ʻoliʻoli. Hoʻohana lākou i nā cranes, nā mea hoʻokaʻawale magnetic, nā kaʻaahi maglev, nā mīkini MRI, a me nā mea electromechanical e like me nā relays a me nā solenoids.
