YUAV UA LI CAS ELECTRICITY Tsim MAGNETISM ? Thaum ib qho hluav taws xob txav mus, nws tsim ib qho chaw thib ob-ib qho chaw sib nqus. Thaum cov electrons raug ua kom ntws mus rau hauv ib qho tam sim no los ntawm tus neeg xyuas pib, xws li ib daim hlau lossis ib lub coil ntawm cov xaim, tus neeg xyuas pib ua ib ntus. hlau nplaum - ib tug electromagnet.
Kuj nug, hluav taws xob tsim Magnetism Yuav ua li cas hlau nplaum tsim hluav taws xob?
Lub zog ntawm txhua lub electron uas yog ib puag ncig los ntawm ib qho hluav taws xob teb tsim lwm daim teb uas hu ua magnetic field. Qhov no yog vim qhov tam sim no ntws los ntawm electrons los ntawm cov hlau conductors, zoo li cov xov hlau, uas ua raws li hlau nplaum . Qhov no yog li cas hluav taws xob tsim magnetism . Yog li, magnetism tsim hluav taws xob.
Dab tsi yog qhov ua rau hlau nplaum? Magnetism yog ua rau los ntawm kev txav ntawm cov nqi hluav taws xob. Txhua yam khoom yog tsim los ntawm cov khoom me me hu ua atoms. Yog vim li cas cov ntaub ntawv xws li ntaub los yog ntawv thiaj li hais tias tsis muaj zog hlau nplaum. Nyob rau hauv cov khoom xws li hlau, cobalt, thiab npib tsib xee, feem ntau ntawm cov electrons spin nyob rau hauv tib txoj kev.
Tsis tas li ntawd, hluav taws xob cuam tshuam li cas rau hlau nplaum?
Hluav taws xob thiab magnetism yog ob ntsig txog phenomena tsim los ntawm electromagnetic quab yuam. Ua ke, lawv tsim electromagnetism. Ib txav hluav taws xob nqi generates ib magnetic teb. Lub magnetic teb induces hluav taws xob nqi zog, tsim ib hluav taws xob tam sim no.
Lub teeb cuam tshuam li cas rau hluav taws xob thiab hlau nplaum?
Teeb yog oscillating hluav taws xob thiab magnetic teb, yog li ntawd hluav taws xob thiab sib nqus. Firstly kev sib cuam tshuam nrog hluav taws xob them thiab thib ob kev cuam tshuam nrog hlau nplaum. Teeb tsis nqa ib qho nqi ntawm nws tus kheej, yog li nws tsis nyiam lossis tshem tawm cov khoom siv hluav taws xob zoo li electrons.

Txoj cai lij choj ntawm kev txuag hluav taws xob siv li cas rau kev hloov hluav taws xob?
Txoj cai lij choj ntawm kev txuag hluav taws xob hais tias lub zog tsis tuaj yeem tsim lossis rhuav tshem - tsuas yog hloov los ntawm ib hom ntawm lub zog mus rau lwm qhov. Qhov no txhais tau hais tias ib qho system ib txwm muaj tib lub zog, tshwj tsis yog nws ntxiv los ntawm sab nraud. Tib txoj kev siv lub zog yog hloov lub zog ntawm ib daim ntawv mus rau lwm qhov
Dab tsi yog cov yam ntxwv ua siab hloov hluav taws xob hloov hluav taws xob LET muaj thaum piv nrog LET hluav taws xob tsawg?
Dab tsi yog cov yam ntxwv ua kom muaj hluav taws xob hloov hluav taws xob siab (LET) hluav taws xob muaj thaum piv nrog cov hluav taws xob qis-LET? Cov huab hwm coj ntau ntxiv, txo qhov nkag mus. (Vim lawv cov nqi hluav taws xob thiab cov khoom loj heev, lawv ua rau ntau ionizations hauv cov ntaub so ntswg, sai sai poob lub zog
Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms?
Tus nqi zoo attracts tus nqi tsis zoo thiab ua rau lwm tus nqi zoo. Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms? Cov nqi hluav taws xob yog cov cuab yeej ntawm tag nrho cov atoms
Lub peev xwm hluav taws xob cuam tshuam li cas rau hluav taws xob teb?
Lub peev xwm hluav taws xob tsuas yog ua haujlwm ua haujlwm ib chav xwb kom txav nws los ntawm ib lub peev xwm mus rau lwm lub peev xwm hauv thaj chaw hluav taws xob. Qhov sib txawv ntawm ob qhov sib txawv equipotentials yog qhov muaj peev xwm sib txawv lossis qhov sib txawv voltage. Electric teb piav txog lub zog ntawm tus nqi
Vim li cas cov kab hluav taws xob ua hluav taws xob yog perpendicular rau equipotential nto?
Txij li cov kab hluav taws xob hluav taws xob taw qhia radiallyaway ntawm tus nqi, lawv yog perpendicular mus rau cov kab hluav taws xob. Lub peev xwm yog tib yam nyob rau hauv txhua txoj kab uas muaj peev xwm, txhais tau hais tias tsis muaj haujlwm yuav tsum tau txav mus los ntawm ib qho ntawm cov kab no
