Peb paub tias kev hloov pauv e.m.f. tuaj yeem tsim los ntawm tig lub kauj nyob rau hauv chaw sib nqus chaw nres tsheblossis los ntawm kev tig lub teb sib nqus hauv ib lub kauj. … Txij li thaum e.m.f. induced nyob rau hauv ib tug coil sib npaug rau tus nqi ntawm kev hloov ntawm flux linkage nrog minus sing.
Yuav ua li cas hloov emf generated piav qhia?
Ib lub tshuab hluav taws xob yog ib qho khoom siv uas tsim hluav taws xob Electromotive Force (e.m.f.) los ntawm kev hloov tus lej ntawm Cov Kab Sib Nqus Flux (Lines of Force), Φ, dhau los ntawm Hlau Coil… Thaum lub kauj yog tig ntawm tus ncej ntawm cov hlau nplaum los ntawm cranking tus kov, AC Voltage Waveform yog tsim.
Kev hloov tam sim no ua li cas?
Kev hloov tam sim no yog tsim los ntawm lub tshuab hluav taws xob … Raws li cov hlau rotates nyob rau hauv lub magnetic teb, qhov hloov lub zog ntawm lub magnetic teb los ntawm cov hlau ua ib tug quab yuam uas tsav cov hluav taws xob nqi nyob ib ncig ntawm cov hlau. Lub zog pib tsim hluav taws xob tam sim no nyob rau hauv ib qho kev taw qhia raws cov hlau.
Kev hloov pauv tam sim no yog dab tsi?
Hloov tam sim no (ac) yog qhov ntws ntawm cov nqi hluav taws xob uas hloov pauv cov kev taw qhia ib ntus. Ib qho ac yog tsim los ntawm kev sib hloov emf, uas yog tsim nyob rau hauv ib lub zog cog, raws li tau piav nyob rau hauv Induced Electric Fields. Yog hais tias qhov chaw ac txawv ib ntus, tshwj xeeb tshaj yog sinusoidally, lub Circuit Court hu ua ac circuit.
Yuav ua li cas yog emf induced nyob rau hauv AC generator?
Ib AC … Lub hauv paus ntsiab lus qab AC generators yog electromagnetic induction. Thaum lub kaw lus kaw yog tig rau hauv ib qho chaw sib nqus nrog nws cov axis perpendicular mus rau magnetic teb, cov hlau nplaum txuas nrog cov kauj hloovthiab ib qho induced emf thiab yog li tam sim no tau teeb tsa hauv nws.
