He aha ka electromagnetic a hoʻokomo

Electromagnetic hoʻokomo mea a pau a puni mākou. A hiki i keia manawa, e like me oe i heluhelu i kēia mau laina mai ka paku o kou lolouila mea, o ka hopena mea ma na keena o ke kino. Eia naʻe, 'oe E mai hopohopo e pili ana ia, no ka mea, kona pinepine' mea ai uuku i mea wale noʻimi naʻauao hoihoi. Eia naʻe, ma lalo o kekahi rula, e mahuahua electromagnetic a hoʻokomo i ka pilikia pae. Ua ua ike ia kanaka ola hilinaʻi nui kuhikuhi ma luna iho. Nolaila, e pono e loaʻa i ka liʻiliʻi loa o kekahi mau manaʻo no ka mea i ka electromagnetic a hoʻokomo.

E ka i ka mea manaʻo hoʻokolohua. No keia, ua pono i ka mea hao apo-O Kaohikukapulani, ma a kekahi mīkiniʻimi e pili ana i ka moʻo ammeter a me ka haahaa mana filament kukui. Kēia O Kaohikukapulani e ia i paʻa loop, ma i hiki kahe ka alternating uilaʻikena. Ke komolima iho Ua kaʻawaleʻana, no ka laʻana, ua ko Yuuki kūlanakauhale i loko o ke ea lākeke. Ka lua o ka nui hehee ai - he lōʻihi uea ma i kaʻikena kahe. Ka hoʻonaʻauao 'aneʻi e e kiʻekiʻe. E kau i ka Hula i loko o kekahi lumi, a me ka uea - i loko o ka 'ē aʻe. ʻae nō hoʻi, ka ammeter i loko o ka'ōlinolino ke komo lima hōʻike 'Aʻohe - io, kahi o kaʻikena malaila?! Ano, i ka uea pololei a hiki i ke apo no ka ihu ... I kēia wahi, ina ke anakahi uila mea ole loa, i ke kui kele ma o ka mea deviates mai Aʻohe. Hana mana! Ma hope o nā mea a pau, na electrons mai ka uea e ole lele ma luna o ka mea hiki ke hooheheeia apo, no ka mea, o ka hope mea mākou pakahi aku la ia kuhikuhi kaʻawale 'ole-lawelawe ea. Mākou complicate mākou hoʻokolohua: uea-eha i ka O Kaohikukapulani. Ano, pua ammeter maopopo Hōʻike ke alo aku o ke apo o ka pilaʻikena. Ke kumu no keia - electromagnetic a hoʻokomo. e wehewehe i ka mea e hanaia mai ka 'epekema wahi o ke hoomaopopo, he mea pono e hana i ka meaʻuʻuku hele i loko o mōʻaukala.

Ka loaʻa o ka electromagnetic a hoʻokomo i ka makahiki 1831 ua wahi ia Michael Faraday. He umi makahiki mua ia, hoi aku la e hoohuli i kaʻume mākenēki ke kahua i loko o uila ikehu, a, i hiki ke ike, brilliantly Makuakane me keia. Kela manawa, i ia manawa, physicists ike i loaʻa nō nāʻano o nā mahinaʻai -ʻume mākenēki a me ka pila nui. Inā 'āhewa' ana nā moku halihali mokulele e hoʻoneʻe, ka mea i kākau kula heʻume mākenēki maoli, a ina immobile, ka electrostatic. He nui nā kanaka hilahila i ka mahinaʻai pono somehow e ua hoʻopili, akā, e hookupaa aku ana i kēia hana, a me kona kuka nei lakou i hana ai me kēia nui Faraday. He neʻe haʻahaʻa'ōwili hao i loko o ka nui. Hopena o kekahi o ia mau mea i pili i ke ana manaʻo, a ma ka 'ē aʻe coils, e kahe ana i ka ikaikaʻikena. Ka hanana o ka huna noi i loko o ka huakai kaapuni a kapaʻonou (ʻonou)ʻikena. Inā (particles) ua directionally e neʻe kauoha, a puni i loaʻa mea heʻume mākenēki kahua. I ka mea, ua hoʻokomo laina o ke kahua ikaika e kela kapa o ka lawelawe huakai kaapuni. Ua hiki ke neʻe aku ia ia iho loop, a me ka mahinaʻai - i ka hopena o ka ia. Hakahaka o ka pololeiʻikena (Faraday ka hoao ana) e alternating hookaaokoa ae mai o kekahi ÿano displacements, e like me ua loaʻa ma ke kula iho loli aʻe me ka manawa. Ka hoʻohana a electromagnetic a hoʻokomo transformers hiki i ka ho okumu ana i uila ikehu. Paha i ka pou makemake loa ua i na wahi kiekie o ka i kēia lā, mai e ia mau manaʻo.

He aha ka ka pilikia i kānaka? Kekahi mana laina laina hoolilo aku na tausani o volts. No ka mea, o keia, ka na kula a puni na kaula e ana i kekahi mau mika. Ke kanaka i hopu ia ma ka ee iaaanu aey ke kahua, e aʻo i kaʻoihana o ka wai nā lātoma ma ka laina o ka hoʻopilikia. Hooloihi ae i waiū i kēia mau ana he kūlana e loli ai na mea he nui kino nenoai.
