Aluminium tubes tuaj yeem tsim hluav taws xob tam sim no hauv kev hloov pauv magnetic teb, qhov tshwm sim ntawm lub hauv paus ntsiab lus ntawm electromagnetic induction. Qhov loj ntawm qhov induced tam sim no nyob ntawm tus nqi ntawm qhov kev hloov ntawm lub magnetic teb thiab conductivity ntawm aluminium raj.
Thaum sib tham txog seb cov raj txhuas puas tuaj yeem tsim hluav taws xob tam sim no, peb yuav tsum xub qhia meej txog lub hauv paus ntsiab lus ntawm electromagnetic induction. Electromagnetic induction yog hais txog qhov tshwm sim uas qhov kev hloov pauv ntawm cov hlau nplaum sib nqus los ntawm lub kaw lus kaw ua rau lub zog hluav taws xob (EMF), uas tuaj yeem tsim tau tam sim no. Lub hauv paus ntsiab lus no tau pom los ntawm Michael Faraday thaum ntxov xyoo pua 19th thiab tau dhau los ua lub hauv paus tseem ceeb ntawm kev tsim hluav taws xob niaj hnub thiab hluav taws xob.
Conductivity ntawm Aluminium Tubes
Aluminium yog tus neeg xyuas pib zoo, txawm hais tias nws cov conductivity qis dua li cov hlau zoo li tooj liab, nws tseem siv dav hauv ntau daim ntawv thov. Raws li tus neeg xyuas pib, cov raj aluminium muaj peev xwm tso cai rau tam sim no hla. Thaum ib lub raj txhuas tau muab tso rau hauv qhov chaw sib nqus hloov pauv, cov hluav taws xob dawb hauv nws tau cuam tshuam los ntawm cov hlau nplaum thiab txav mus, yog li tsim EMF thiab tam sim no.
Sib nqus teb hloov pauv thiab Induced Current
Rau ib lub raj txhuas los tsim kom muaj qhov cuam tshuam tam sim no, kev hloov pauv magnetic yog tsim nyog. Qhov kev hloov pauv hauv qhov chaw sib nqus no tuaj yeem tshwm sim los ntawm qhov chaw sib nqus sab nraud (xws li cov hlau nplaum tsim los ntawm kev hloov tam sim no) lossis los ntawm kev txav ntawm lub raj aluminium nws tus kheej (xws li txiav cov kab hlau nplaum). Thaum lub magnetic teb hloov, ib tug induced electromotive quab yuam yog generated nyob rau hauv lub txhuas raj, uas nyob rau hauv lem drives tiam tam sim no.
Daim ntawv thov thiab kev txwv ntawm Induced Tam sim no Lub induced tam sim no generated los ntawm txhuas raj muaj ntau yam kev siv nyob rau hauv cov ntaub ntawv siv. Piv txwv li, nyob rau hauv generators, lub rotating txhuas raj (los yog lwm yam conductor) txiav magnetic teb kab los tsim ib tug induced tam sim no, yog li hloov txhua yam zog rau hauv hluav taws xob zog. Txawm li cas los xij, qhov loj ntawm qhov induced tam sim no kuj txwv. Ua ntej, qhov ceev ntawm qhov kev hloov ntawm lub magnetic teb, qhov loj ntawm induced tam sim no. Qhov thib ob, qhov conductivity ntawm aluminium raj kuj cuam tshuam qhov loj ntawm qhov induced tam sim no. Tsis tas li ntawd, lub xub ntiag ntawm kev tiv thaiv los yog tsis xws luag nyob rau hauv lub aluminium raj yuav ua rau kom txo los yog poob ntawm induced tam sim no.
