thaum magnetic flux hloov

Sib nqus flux yog qhov ntsuas ntawm tag nrho cov magnetic teb uas dhau los ntawm ib cheeb tsam muab. Nws yog ib yam khoom ntawm lub zog magnetic teb thiab cheeb tsam nws hla. Chav tsev ntawm magnetic flux yog Weber (Wb).

Lub flux tuaj yeem hloov pauv nyob rau hauv lub xub ntiag ntawm ib tug hloov magnetic teb, raws li Faraday txoj cai ntawm electromagnetic induction. Txoj cai lij choj no hais tias thaum tus neeg xyuas pib txav los ntawm qhov chaw sib nqus, nws muaj kev hloov pauv hauv cov hlau nplaum sib nqus. Qhov no ua rau muaj kev tsim hluav taws xob lossis hluav taws xob hluav taws xob (EMF) hauv tus neeg xyuas pib.

Tus nqi ntawm kev hloov pauv ntawm magnetic flux yog proportional rau induced EMF. Lub hauv paus ntsiab lus no yog siv dav hauv ntau daim ntawv thov, xws li hauv transformers, generators, thiab motors.

Cov kev taw qhia ntawm kev hloov pauv hauv cov hlau nplaum yog nyob ntawm qhov kev taw qhia ntawm cov hlau nplaum thiab cov lus tsa suab ntawm tus neeg xyuas pib. Yog hais tias tus neeg xyuas pib tau txav mus rau qhov chaw sib nqus, qhov kev hloov pauv hauv flux yog qhov siab tshaj plaws. Yog hais tias tus neeg xyuas pib tau txav mus rau qhov sib nqus ntawm qhov sib nqus, tsis muaj kev hloov pauv hauv flux.

Qhov loj ntawm qhov induced EMF kuj nyob ntawm qhov kev hloov pauv ntawm cov hlau nplaum sib nqus. Yog li ntawd, qhov ceev ntawm qhov sib nqus flux hloov, qhov siab dua yog induced EMF.
