Taw qhia rau Electromagnetic Physics
Electromagnetism yog ib ceg ntawm lub cev uas kawm txog kev sib cuam tshuam ntawm hluav taws xob thiab lub zog sib nqus, thiab nws cov cai thiab kev siv. Raws li qhov pom ntawm cov niaj hnub physics, qhov tshwm sim ntawm cov hlau nplaum yog tsim los ntawm lub zog nqe, thiab yog li cov ntsiab lus ntawm cov hlau nplaum yuav tsum muaj nyob rau sib txawv qib hauv qhov hluav taws xob. Yog li, cov ntsiab lus ntawm electromagnetism thiab hluav taws xob yog qhov nyuaj kom muab faib tag nrho, thiab "hluav taws xob" qee zaum hu ua "electromagnetism". Kev siv tshuab hluav taws xob tau hloov zuj zus los ntawm ob qhov kev kawm sib txawv (hluav taws xob, lub zog hluav taws xob) rau hauv ib qho hauv physics. Lub tuam txhab kev qhuab qhia tag nrho yog ua raws li ob qho kev tshawb pom tseem ceeb, uas yog lub zog sib nqus ntawm qhov tam sim no thiab hluav taws xob los ntawm qhov kev hloov pauv chaw. Ob qhov kev sim no tshwm sim, ua ke nrog Maxwell qhov kev xav ntawm cov hlau nplaum tsim los ntawm thaj chaw hloov hluav taws xob, tau tso tag nrho cov txheej txheem thev naus laus zis ntawm kev siv hluav taws xob thiab tsim cov khoom siv hluav taws xob thiab hluav taws xob uas muaj qhov cuam tshuam zoo rau kev hloov kho tshiab hauv lub ntiaj teb.
Qhov tam sim no nqa los ntawm cov hlau tsim lub sib nqus ib puag ncig nws, thiab cov kab sib nqus ib puag ncig cov hlau nyob rau hauv cov qauv sib txawv.
Qhov tam sim no tuaj yeem ntsuas ncaj qha siv ammeter. Qhov tsis zoo ntawm hom no yog qhov Circuit Court yuav tsum raug txiav tawm thiab muab tso rau qhov ntsuas nruab nrab hauv qhov nruab nrab ntawm Circuit Court. Sib quas ntus ntsuas ntawm cov hlau nplaum ncig ncig ntsuas tam sim no tuaj yeem ntsuas qhov sib txawv tam sim no. Qhov zoo dua yog tias tsis tas yuav txiav lub Circuit Court. Cov twj paj nruag uas siv cov qauv no los ntsuas tam sim no suav nrog Hall effect sensors, clamps tam sim no, hloov tam sim no, Rogowski coils, thiab cov zoo li.
Kev tshawb pom ntawm hluav taws xob sib xyaw ua ke qhov kev tshawb xav ntawm electromagnetism thiab atomic qauv nrog teeb meem. Lorentz txoj kev xav ntawm cov hluav taws xob ntuas cov xim loj kawg electroscopic electromagnetic cov teeb meem ntawm cov teeb meem rau qhov cuam tshuam ntawm cov hluav taws xob hauv qhov tsis muaj hluav taws xob, thiab cov teeb meem ib yam piav txog qhov tshwm sim ntawm hluav taws xob, kev tsim hluav taws xob, thiab lub teeb ci.
Kev Siv Hluav Taws Xob yog ib ceg ntawm physics. Muaj qhov sib txuas ua ke ntawm hluav taws xob thiab hlau nplaum sib txawv. Kev siv hluav taws xob dav dav tuaj yeem hais tau suav nrog hluav taws xob thiab kev sib nqus, tab sis kev txiav txim siab nqaim nws yog kev qhuab qhia uas tshawb nrhiav qhov cuam tshuam ntawm hluav taws xob thiab cov hlau nplaum. Nws feem ntau yog kawm txog electromagnetic tsis, hluav taws xob teb thiab lwm yam nqi hluav taws xob, kev ua haujlwm ntawm cov khoom them, thiab lwm yam.
