Ke noʻonoʻo ʻoe i kahi magnet, hiki paha iā ʻoe ke nānā nui i kona hiki ke hoʻowalewale a hoʻokuke paha i nā mea ʻē aʻe.Eia naʻe, ua ʻike anei ʻoe he kuhikuhi kikoʻī ko ka magnetization?E ʻimi hohonu kākou i ka honua o ka magnetism a e ʻimi i ke kuhikuhi magnetized a me ka magnetization o kahi magnet.
ʻO ka hoʻomaka ʻana, ʻo ka magnetization ke kaʻina hana o ka hana ʻana i kahi māla magnetic i loko o kahi mea.Hoʻokumu ʻia ka māla magnetic ma muli o ka alignment o nā electrons i ka mea.I ka neʻe ʻana o nā electrons i ka ʻaoʻao hoʻokahi, hana lākou i kahi māla magnetic, a i ka hopena hopena i kahi magnet.Ma nā ʻōlelo maʻalahi, ʻo ka magnetization ka hana o ka hana ʻana i kahi magnet.
I ka manawa e hoʻohana ʻia ai ka magnet, loaʻa iā ia kahi kuhikuhi kikoʻī o ka magnetization.ʻO kēia ke kuhikuhi i hoʻopaʻa ʻia nā electrons, a hoʻoholo i ke ʻano magnetic o ka magnet.No ka laʻana, inā loaʻa iā ʻoe kahibar magnet, e pili ana ke kuhikuhi magnetization ma ka lōʻihi o ka pā.
Ma waho aʻe o ka kuhikuhi ʻana i ka magnetization, ʻelua mau pou magnet - ʻākau a hema.Hoʻokomo ʻia ka pole ʻākau i ka pole hema o kekahi magnet, a ʻo ka pole ʻākau ke kiʻi aku i ka pole ʻākau o kekahi magnet.Pela no ka pole hema.Ua kapa ʻia kēia ʻano he polarity magnetic.
I kēia manawa, e komo kāua i loko o ka nitty-gritty o ka hopena o ke kuhikuhi magnetized i ka ʻano o kahi magnet.ʻO ke kuhikuhi magnetization o kahi magnet e hoʻoholo ai i ka ikaika o kāna māla magnetic.Ke hele ka ʻaoʻao o ka magnetization ma ka lōʻihi o kahi pahu magnet, e hopena ia i kahi māla ikaika.Ma ka ʻaoʻao ʻē aʻe, inā ʻoi aku ka ʻaoʻao o ka magnetization i ka laula o kahi magnet, e hopena ia i kahi māla palupalu nāwaliwali.
Eia kekahi, pili pū ka kuhikuhi magnetization i nā waiwai magnetic o kahi magnet.No ka laʻana, ʻike ʻia ka magnet me kona kuhikuhi hoʻoneʻe ʻana mai ka pole ʻākau a i ka pole hema ma ke ʻano he magnet "maʻamau".Hoʻopaʻa ʻia kēia mau magnet i ko lākou māla ma hope o ka wehe ʻana i ke kahua i hoʻopaneʻe iā lākou.
I ka hoʻohālikelike ʻana, ua kapa ʻia kahi magnet me kāna kuhikuhi magnetization a puni ka pōʻai o ka cylinder he "demagnetized" magnet.Nalo koke kēia mau mākēneki ma hope o ka wehe ʻana i ke kahua mākēneki i hoʻopaneʻe iā lākou.He mea pono kēia waiwai no nā noi he nui, e like me nā ʻāpana kāleka hōʻaiʻē a me nā pahu paʻakikī kamepiula.
ʻO ka holoʻokoʻa, ʻo ke kuhikuhi magnetized a me ka magnetization ʻelua mau mea koʻikoʻi o ke ʻano o ka magnet ʻaʻole pono e mālama ʻia.ʻO ka hoʻomaopopo ʻana i kēia mau manaʻo hiki ke kōkua iā ʻoe e hoʻoholo i ke koho ʻana i nā magnet no nā noi like ʻole.Eia kekahi, hiki iā ia ke hāʻawi i ka ʻike pehea e hoʻohana ʻia ai nā magnet i ʻoi aku ka maikaʻi a me ka maikaʻi.
No ka hōʻuluʻulu manaʻo, ʻo ka magnetization ke kaʻina hana o ka hana ʻana i kahi māla magnetic i loko o kahi mea, a ʻo ke kuhikuhi magnetized ʻo ia ke kuhikuhi e hoʻopili ʻia ai nā electrons.Hoʻopili pololei kēia i ka ikaika a me nā waiwai o ke kahua magnetic o ka magnet.Hoʻoholo ʻia ka polarity ma ka ʻākau a me ka ʻaoʻao hema o kahi magnet, ka mea e huki a hoʻolei paha i nā mea magnet ʻē aʻe.Ma ka hoʻomaopopo ʻana i kēia mau manaʻo, hiki iā mākou ke mahalo i ka paʻakikī o nā magnet a me ko lākou koʻikoʻi i ko mākou ola i kēlā me kēia lā.
