Qhov kev xav tau yooj yim rau induce emf hauv lub kauj yog tus nqi ntawm cov hlau nplaum txuas nrog lub kauj yuav tsum hloov.
Yuav ua li cas thiaj tsim tau emf?
Tus induced emf tuaj yeem tsim los ntawm kev hloov pauv:
- (i) magnetic induction (B),
- (ii) thaj chaw uas nyob ze ntawm lub kauj (A) thiab.
- (iii) kev taw qhia ntawm lub kauj (θ) nrog rau qhov sib nqus.
Qhov laj thawj ntawm kev ntxias emf yog dab tsi?
Qhov laj thawj tseem ceeb tshaj plaws ntawm kev ntxias EMF yog hloov pauv hauv magnetic flux. … Muab cov khoom nqa tam sim no uas txav mus tas li hauv qhov chaw ruaj khov thiab zoo li qub. Qhov no yuav ua rau muaj kev hloov pauv hauv cheeb tsam vector thiab yog li, EMF yuav raug tsim.
Thaum induced emf yog tsim nyob rau hauv ib kauj?
Ib emf yog induced nyob rau hauv lub kauj thaum ib tug bar hlau nplaum raug thawb rau hauv thiab tawm ntawm nws. Emfs ntawm cov paib sib txawv yog tsim los ntawm kev txav mus rau qhov sib txawv, thiab cov emfs kuj tau thim rov qab los ntawm cov ncej rov qab. Cov txiaj ntsig zoo ib yam yog tsim yog tias lub kauj yog txav ntau dua li cov hlau nplaum-nws yog cov lus sib txheeb uas tseem ceeb.
Dab tsi tshwj xeeb induces ib qho emf hauv ib kauj?
Raws li pom hauv Atoms dhau los, kev hloov pauv hauv cov hlau nplaum sib nqusua rau lub zog hluav taws xob (EMF) tawm tsam qhov kev hloov pauv-tus txheej txheem hu ua induction. Motion yog ib qho ntawm cov laj thawj tseem ceeb ntawm induction. Piv txwv li, ib tug hlau nplaumtsiv mus rau ib lub kauj induces EMF, thiab lub kauj txav mus rau lub hlau nplaum tsim ib qho EMF zoo sib xws.
