A hloov magnetic teb induces ib tug tam sim no nyob rau hauv ib tug conductor. Piv txwv li, yog tias peb txav ib lub bar hlau nplaum Nyob ze ntawm lub voj voog conductor, ib qho tam sim no tau txais induced hauv nws. The E. M. F. E induced nyob rau hauv lub voj voog yog sib npaug rau tus nqi ntawm qhov flux ϕ los ntawm lub voj kev hloov nrog lub sijhawm.

Raws li txoj cai, qhov hloov hluav taws xob ua haujlwm li cas?

Txij li thaum a hloov Sib nqus teb tsim ib hluav taws xob teb thiab a hloov hluav taws xob teb tsim cov hlau nplaum teb , ob tug oscillating teb txuas ntxiv txhawb ib leeg, thiab nthwv dej propagates los ntawm qhov chaw.

Ib yam li ntawd, txoj kev sib txawv ntawm kev hloov magnetic teb yog dab tsi? Qhov no hloov tej zaum yuav raug tsim nyob rau hauv ob peb txoj kev ; koj ua tau hloov lub zog ntawm cov magnetic teb , txav tus neeg xyuas pib hauv thiab tawm ntawm qhov teb , hloov qhov kev ncua deb ntawm a hlau nplaum thiab tus neeg xyuas pib, los yog hloov thaj tsam ntawm ib lub voj nyob hauv ib qho chaw ruaj khov magnetic teb.

Tib neeg kuj nug, dab tsi ib txwm ua ib qho chaw sib nqus?

Cov nqi txav taw tes, xws li electrons, tsim tawm nyuaj tab sis paub zoo magnetic teb uas nyob ntawm tus nqi, tshaj tawm, thiab acceleration ntawm cov khoom. Sib nqus teb kab tsim nyob rau hauv concentric voj voog nyob ib ncig ntawm ib tug cylindrical tam sim no-nqa conductor, xws li ib tug ntev ntawm cov hlau.

Puas yog lub sijhawm sib txawv ntawm cov hlau nplaum tsim hluav taws xob?

Xyoo 1831, Michael Faraday nrhiav tau qhov ntawd, los ntawm sib txawv magnetic teb nrog sij hawm , ib hluav taws xob teb tau raug tsim tawm. Qhov tshwm sim yog hu ua electromagnetic induction.
