Core Electromagnetic Induction Txoj Cai

 

Lub hwj chim transformer ua haujlwm rauFaraday Txoj Cai ntawm Electromagnetic Induction:

Thaum cov thawj winding txuas nrog AC fais fab mov, ib qho kev hloov tam sim no ntws los ntawm cov winding, tsim ib qho sib nqus sib nqus flux hauv cov tub ntxhais hlau.

 

Qhov sib nqus flux txuas ob qho tib si thawj thiab theem nrab windings, inducing electromotive force (EMF) ntawm tib zaus nyob rau hauv ob qho tib si windings.

Yog hais tias qhov thib ob winding txuas nrog lub load, tam sim no ntws los ntawm lub load, converting magnetic zog rov qab mus rau lub zog hluav taws xob. Qhov no ua tiav cov txheej txheem ntawm kev hloov hluav taws xob hluav taws xob los ntawm lub zog hluav taws xob mus rau qhov chaw thau khoomtsis hloov zaus.
