YElectromagnetic Induction vs Sib Nqus Induction

Electromagnetic induction thiab magnetic induction yog ob lub ntsiab lus tseem ceeb hauv electromagnetic teb txoj kev xav. Kev siv ntawm ob lub tswv yim no muaj ntau heev. Cov kev xav no tseem ceeb heev txawm tias hluav taws xob yuav tsis muaj yog tsis muaj lawv. Kab lus no yuav tham txog qhov sib txawv ntawm electromagnetic induction thiab magnetic induction.

Magnetic Induction yog dab tsi?

Sib nqus induction yog txheej txheem ntawm kev sib nqus ntawm cov khoom hauv qhov chaw sib nqus sab nraud. Cov ntaub ntawv tuaj yeem muab faib ua ntau pawg raws li lawv cov khoom sib nqus. Paramagnetic cov ntaub ntawv, Diamagnetic cov ntaub ntawv thiab Ferromagnetic cov ntaub ntawv yog rau npe ob peb. Kuj tseem muaj qee yam tsawg dua xws li cov khoom siv tshuaj tiv thaiv ferromagnetic thiab cov ntaub ntawv ferrimagnetic. Diamagnetism yog qhia nyob rau hauv atoms nrog tsuas yog khub electrons. Tag nrho cov spin ntawm cov atoms yog xoom. Cov khoom sib nqus tshwm sim tsuas yog vim lub orbital motion ntawm electrons. Thaum cov khoom siv diamagnetic muab tso rau hauv qhov chaw sib nqus sab nraud, nws yuav tsim cov hlau nplaum tsis muaj zog heev los tiv thaiv kev sib luag rau sab nraud. Paramagnetic cov ntaub ntawv muaj atoms nrog unpaired electrons. Lub tshuab hluav taws xob ntawm cov hluav taws xob tsis sib xws no ua raws li cov hlau nplaum me me, uas muaj zog heev dua li cov hlau nplaum tsim los ntawm electron orbital motion. Thaum muab tso rau hauv ib qho chaw sib nqus sab nraud, cov hlau nplaum me me no ua ke nrog lub tshav pob los tsim ib qho chaw sib nqus, uas yog sib npaug rau sab nraud. Ferromagnetic cov ntaub ntawv tseem yog cov ntaub ntawv paramagnetic nrog thaj tsam ntawm cov hlau nplaum dipoles hauv ib qho kev taw qhia txawm tias ua ntej siv cov hlau nplaum sab nraud. Thaum siv cov teb sab nraud, cov cheeb tsam sib nqus no yuav ua kom lawv tus kheej ua ke mus rau lub tshav pob kom lawv yuav ua rau thaj chaw muaj zog. Ferromagnetism tshuav nyob rau hauv cov khoom txawm tias tom qab sab nraud teb raug tshem tawm, tab sis paramagnetism thiab diamagnetism ploj mus sai li sai tau thaum lub teb sab nraud raug tshem tawm

Electromagnetic Induction yog dab tsi?

Electromagnetic induction yog cov nyhuv ntawm tam sim no ntws los ntawm tus neeg xyuas pib, uas txav mus los ntawm qhov chaw sib nqus. Txoj cai Faraday yog txoj cai tseem ceeb tshaj plaws txog qhov tshwm sim no. Nws hais tias electromotive quab yuam tsim nyob ib ncig ntawm ib txoj kev kaw yog proportional rau tus nqi ntawm kev hloov ntawm cov hlau nplaum flux los ntawm tej nto bounded los ntawm txoj kev ntawd. Yog tias txoj kev kaw yog lub voj voog ntawm lub dav hlau, tus nqi ntawm kev sib nqus flux hloov ntawm thaj tsam ntawm lub voj yog proportional rau lub electromotive quab yuam generated nyob rau hauv lub voj. Txawm li cas los xij, lub voj no tsis yog qhov chaw khaws cia tam sim no; yog li ntawd, cov kev cai lij choj ntawm hluav taws xob xws li Kirchhoff txoj cai tsis siv rau hauv qhov system no. Nws yuav tsum tau muab sau tseg tias ib tug khov kho magnetic teb nyob rau saum npoo yuav tsis tsim ib tug electromotive quab yuam. Lub magnetic teb yuav tsum sib txawv nyob rau hauv thiaj li yuav tsim lub electromotive quab yuam. Qhov kev xav no yog lub ntsiab lus tseem ceeb tom qab tsim hluav taws xob. Yuav luag tag nrho cov hluav taws xob, tshwj tsis yog los ntawm lub hnub ci hlwb, yog tsim los siv cov txheej txheem no.

Qhov txawv ntawm electromagnetic thiab magnetic induction yog dab tsi?

• Sib nqus induction yuav lossis tsis tuaj yeem tsim cov hlau nplaum ruaj khov. Electromagnetic induction ua ib qho tam sim no kom cov generated tam sim no tawm tsam qhov kev hloov hauv magnetic teb.

• Sib nqus induction tsuas yog siv cov hlau nplaum thiab cov khoom sib nqus, tab sis electromagnetic induction siv hlau nplaum thiab circuits.
