Eddy Current vs Induced Current
Eddy tam sim no thiab induced tam sim no yog ob lub ntsiab lus tseem ceeb hauv electromagnetic teb txoj kev xav. Ob lub tswv yim no muaj ntau yam kev siv hauv ntau yam. Kab lus no yog hais txog lub hauv paus ntawm eddy tam sim no thiab induced tam sim no thiab qhov sib txawv ntawm ob lub tswv yim.
Yuav Ua Li Cas Tam Sim No?
Kev nkag siab ntawm electromagnetic induction yog qhov tseem ceeb, kom nkag siab qhov cuam tshuam tam sim no. Electromagnetic induction yog cov nyhuv ntawm cov dej ntws los ntawm tus neeg xyuas pib, uas txav mus los ntawm qhov chaw sib nqus. Txoj cai Faraday yog txoj cai muaj hwj chim 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 voog 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, txawm tias nws muaj zog 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 lub hnub ci hlwb, yog tsim los siv cov txheej txheem no. Lub teb hluav taws xob tsim los ntawm electromagnetic induction yog qhov tsis muaj kev saib xyuas. Yog li ntawd, cov kev cai lij choj hauv cheeb tsam xws li Kirchhoff txoj cai tsis siv tau nyob rau hauv induced teb. Rau thaj chaw uas tsis yog kev saib xyuas, ib qho taw tes tuaj yeem muaj ob qhov txiaj ntsig.
Eddy Tam sim no yog dab tsi?
Ib qho eddy tam sim no yog tsim thaum tus neeg xyuas pib raug rau qhov chaw sib nqus hloov pauv. Eddy tam sim no tseem hu ua Foucault tam sim no. Cov tam sim no feem ntau yog tsim nyob rau hauv me me kaw loops hauv tus neeg xyuas pib. Ib qho eddy txhais tau hais tias lub voj voog turbulence. Lub zog ntawm eddy tam sim no nyob ntawm lub zog thiab tus nqi ntawm kev hloov pauv ntawm cov hlau nplaum thiab cov khoom siv hluav taws xob. Eddy tam sim no poob yog txoj hauv kev tseem ceeb ntawm lub zog poob hauv transformers. Yog hais tias tsis yog rau qhov eddy tam sim no poob, transformers yuav muaj efficiency ze li ntawm 100%. Lub eddy tam sim no poob nyob rau hauv transformers yog minimized los ntawm kev siv tsis tshua muaj neeg nyias nyias daim hlau thiab muaj huab cua nyob rau hauv txoj kev ntawm eddy tam sim no. Eddy tam sim no tsim ib qho chaw sib nqus tawm tsam qhov kev hloov pauv hauv magnetic teb. Qhov tshwm sim ntawm eddy tam sim no yog siv nyob rau hauv daim ntawv thov xws li sib nqus levitation, kev txheeb xyuas ntawm cov hlau, txoj hauj lwm sensing, electromagnetic braking thiab structural testing. Cov eddy tam sim no ntawm tus neeg xyuas pib kuj yog nyob ntawm daim tawv nqaij nyhuv ntawm cov hlau.
Qhov txawv ntawm eddy tam sim no thiab induced tam sim no yog dab tsi?
• Eddy tam sim no tsim nyob rau hauv cov khoom, thiab induced currents yog tsim nyob rau hauv ib tug kaw Circuit Court.
• Eddy tam sim no yog ywj siab ntawm thaj tsam ntawm tus neeg xyuas pib, tab sis cov khoom siv hluav taws xob yog nyob ntawm thaj tsam ntawm lub voj voog.
• Induced currents xam tau tias yog tus nqi ntawm eddy tam sim no generated nyob rau hauv cov khoom.
