He aha ka ke Lorentz ikaika

He aha ka ka Lorentz paa? Hoi i noonoo ai i keʻano o ka papa e permeate laina ka nui o ka electromagnetic a kula. Inā 'oe i loko o kēia wahi o kekahi uila uku ole (ka mea hiki e like kula haʻahaʻaa huna, a me ka papa kino), a laila ka mea, e haawiia mai e ai i ka hopena o ka F, i kapaia "Lorentz ikaika". Kekahi o na ki kumu - o ke alo o ka huna hoʻonui. Ma nā hua'ōlelo, ke kauoha Ua hoʻoneʻe. Aia He He haʻilula no ka laulā manao paa o konaʻikena waiwai:

F = Q * (E + ((1 / c) * V) * B),

kahi Q - e malama; E - ka nui o ka uila kahua; B -ʻume mākenēki kahua ikaika; V - māmā holo o ka huna e lawe ana i ka oihana; l - he a eia i ka mämä holo o ka malamalama.

He mea pono i kekahi o na mea ia e hoohalike. Aia He He oi eiiieaen kākau ia, hiki i ka ke Lorentz pūʻali koa, o ke kuhikuhi ana vectors, a me kā lākou mau uea 'i komo e hooholo.

E like me ka mua i olelo ia (a ike, mai na nā papakuhikuhi), ia mea mau Kuleana neʻeʻana. Ka nui, e hoike ana i ke kauoha ana ma muli o ia kona AaOIeIOUIeXAOAaIN me ke kula i laila o ka EMF (electromotive ikaika). A ka mea, aole ia i mea i ke ano o ka hopena, nāna i hāpai i ka hele (umekaumaha, ka hewa a hana ma luna o kekahi i kekahi, a no laila, ma luna o.).

Ke hoʻohālikelike a me nā hana, ka Lorentz ikaika ua pololei correlated me na hopena a o Lenz a me ka hoʻokuleana i kona rula. Hoole i ka pā o ka hope. I ka hana mana a ma ka electromotive ikaika ma luna o ka neʻeʻana mālama i loko o ke kula, mau aʻo i kaʻoihana i loko o ia ke alanui (ia mea he maʻi lele nui), e pale aku i kekahi loli ma ka hoʻonui.

I kekahi ke olelo aku i ka Lorentz ikaika ua nānā 'ia e ka Coulomb AaOIeIOUIeXAOAaIN o ka' āhewa 'ana, a elua hou eiiiiiaiou pili me ka noi o - ololi kaʻume mākenēki a me ka uila kahua ikaika. Nō kāu, no ka wehewehe ana i na keʻano o ka hanaʻana ka hoʻohana 'ana i nā kēia ho: ma kaʻume mākenēki kula me ka hoʻokomo vectors B aia no he Hoʻohana alakaʻi mele lōʻihi L a me keʻa-mahele wahi S, ma a ka uila he I. hope' ana hilinaʻi nui ma luna o ka nui Q o ka uku ole nā moku halihali mokulele maalo ae la oia ma ka pa alima ka leo no i kekahi manawa ( 'o ia hoʻi, ma ka mämä holo V). Nolaila, ke koi ikaika (Lorentz) o ka lākiō o ka mea mawaho ikaika, ka hopena ma luna o kēlā me kēiaʻoihana lawe i loko o ka hāʻawi buke a hiki i ka helu o ka uku ole conductors.

Inā ka maʻi lele mea mākou noonoo, ka Lorentz ikaika ua mau kauoha p ÷ haku i ka olelo a me ka māmā o ka hoʻokomo. He loa oluolu e oholo kona kohoʻia, ina ka luawai-ike mākou hoʻohana hema-lima noho alii ana. E hana i kēia, mentally poho o kona lima hema kau e hiki mai ana i ke alakaʻi mele no laila, ua eha manamana hōʻike i ka olelo ma i uilaʻikena lua i pele, a me ka maʻi lele o ka hoʻokomo kahua i kauoha p ÷ haku i ka pama. E like me ka hopena o ka manamana nui (akau huina a me ke koena), e kuhikuhi ana i ka poe maʻi lele hana ma luna o ka 'āhewa' ana. Kekahi o nā hiʻona o keia ikaika ka mea e hoʻololi wale i ka olelo o ka māmā holo maʻi lele o kela a me keia o ka papa (particles), oiai e hoʻololi i ka ikaika o ka noi (kinetic ikehu).

Ma hope o ka manawa ma hope o ka puka i loaʻa, a me ka pono o ka Lorentz ikaika. Kekahi o ka loa kaulana - o kona hoike ana i loko o ka Hall kanawai. Mamuli o ia mea i loko o keia offset kŰia i, a me ka helehelena o Loaʻaʻia ka uku ole i ka lawelawe papa (lipine). Ka Hall hookoia ua hoʻomano hoʻohana 'ia i loko o nā ana manaʻo a me nā mea e loaʻa ka mea nalo. I ke kumukuai o 'ana i kumumanaʻo o ka loina o ka hana CRT CRT e hoʻohana i ka deflection kanawai directionalʻume mākenēki ke kahua ma ka neʻe kauoha (particles) kinoea ma na nā uila aʻa lolo ( "pū") no electrons lole komoʻuʻuku nona phosphor' ilikai e deflected i ka nui o kona mau wahi i ikeia kaʻoi loa ma muli o i ka AaOIeIOUIeXAOAaIN kahua laina a me ka malama i luli (particles) .
