ʻume mākenēki koko

E ho ohana i ka mana laina,ʻaʻole wale nō ke hōʻike i ka olelo o kaʻume mākenēki kula, akā, no hoi, e emi iho i ka nui o kona hoʻokomo.

Mākou i hoʻonohonoho ai, e lawe mai i ka laina o ka mana no laila, ua ma 1 cm² āpana ÷ haku hoʻokomo maʻi lele ma ka kekahi wahi, i ka helu o ka laina e paa like kahua ikaika ma ia wahi.

Ma ka wahi ma ke kahua ikaika, e kela aku kona nui, i ka mahinaʻai laina i ka pūhaka. Conversely, ma ke kahua ikaika mea emi emi a me ka mana laina.

Ke'ōlelo mai, no ka paʻapū o kaʻume mākenēki kula laina e hookolokoloia mai ai au ma luna o kona hoʻokomo maʻi lele nui, a me ka olelo o ka laina o ka mana - o ka olelo o ka maʻi lele.

Kilo ana i ka pololeiʻikenaʻume mākenēki spectra coils Hōʻike i ka wehe 'ana o ke alakaʻi mele kaʻume mākenēki ke kahua emi, eia hoi, nui koke.

Aʻume mākenēki kahua me ka hoʻokomo kaiʻewaʻewa i kekahi mau kumu i kapaʻia heterogeneous. Field mea he nonuniform kahua mea rectilinear a me ka hoʻopoepoeʻikena kahua mawaho o ka solenoid, ke kahua o ka paʻa Mākēneki , etc.

Keʻume mākenēki ke kahua o ka ia i nā mea nui o ke hoʻokomo mea homogeneous kahua. Graphically homogeneousʻume mākenēki kahua poe ma ka mahinaʻai laina e ho i like liuliu, ia laua laina.

An kumu o kaʻaʻahu ke kahua o ke kula, a hiki i ka loko o ka lōʻihi'ōwili hao, e like me ka mahinaʻai ma waena o ka pono-kaulike ia laua planar laau maka o ka electromagnet.

Ke huahana o kaʻume mākenēki kula penetratingʻeleu kaapuni ma ka huakai kaapuni wahi ua kapaia kaʻume mākenēki koko o kaʻume mākenēki hoʻokomo 'ole waleʻume mākenēki koko.

Hoʻoholo 'haawi aku la ia, a aʻo i nā waiwai o ka' ōlelo Pelekānia physicist - Faraday. He 'ike akula i kēia manaʻoʻo ia ka mea e hiki ai i ka hou noonoo i ka hoʻokahiʻano o kaʻume mākenēki a me ka pila nuiʻike manaʻo.

Denoting kaʻume mākenēki koko ma ka palapala F, ka contour wahi S, a me ka huina ma waena o ka olelo o ka maʻi lele o ka hoʻokomo B a me ka mea maʻamau N a hiki i ka loop kahi α, ke kēia helu kaulike hiki ke palapalaia.

F = B S cos α.

ʻume mākenēki koko - mea he scalar a pau.

Mai kākou i ka pa apŘ o ka mana laina o ākeʻakeʻa kumuʻume mākenēki kahua kona hoʻokomo, kaʻume mākenēki koko like me ka holoʻokoʻa helu o nā laina o ka poe ikaika no lakou e komo iloko o ka hana huakai kaapuni.

Me ka loli i loko o ke kula, a me ka hoʻololi i kaʻume mākenēki koko i komo iloko o ka huakai kaapuni: ka amplification kahua ia maoli he wā hemohemo - emi iho.

Ke pa alima oʻume mākenēki koko i loko o ka Si loaa kahawai a komo iloko o ka wahi o ka 1 m² a me ka i ana ma ka homogeneousʻume mākenēki kahua me ka hoʻokomo o ka 1 Wb / m², a me ka mea p ÷ haku i ka maʻi lele o ka hoʻokomo. Oia ka pa alima ua kapaia Weber

1 Wb = 1 Wb / m² ˖ 1 m².

Loli konaʻume mākenēki koko paha ke he uila kahua ka laina o ka poe ikaika no lakou i hoopili (vortex uila kahua). Kēia kahua ikeia ma WindowsʻImi Loa me ka hana ana o na koa. O kŰia ua kapaia electromagnetic a hoʻokomo, a me ka electromotive ikaika ua loaʻa i ka mea ia manawa - EMF hoʻokomo.

A eia hoi, ka mea e e kaulana i kaʻume mākenēki kokoʻo ia ka mea hiki, e emi iho i ka pono a pau Mākēneki ( 'ole kekahi' ē aʻe kumu oʻume mākenēki mahinaʻai). No ia mea, ina o ka ʻume mākenēki koko nuʻa ʻo ia ka mea e hiki ai i ka i emi iho kona kanawai i kekahi i kekahi wahi, i kaʻume mākenēki koko - like me ka a pau. Ie, ka mea hiki ke olelo mai i keia mea i ka lua o ka loa nui ano o kaʻume mākenēki kahua. Nolaila, ina kaʻume mākenēki koko nuʻa hana me ka mana ano o kaʻume mākenēki kula, kaʻume mākenēki koko - o kona ikehu ano.

Hoi mai i ka ho'āʻoʻana, ua hiki no hoi ke olelo i hiki ke noonoo kela huli o ka'ōwili hao me he kaawale ia he vicious huli. Ka Ia kaapuni, ma ka mea e hele aku i kaʻume mākenēki koko o kaʻume mākenēki hoʻokomo. Ma ia ka hihia, e e ia i hoʻokomo pila nuiʻikena. Penei, ia mea ma lalo o ka aoao o kaʻume mākenēki koko ua loaʻa uila mahinaʻai i loko o ka paʻa alakaʻi mele. A laila, i kēia uila kahua paha ke ka pila nuiʻikena.
