Txhais kev sib nqus ua lej. Qhov no yuav qhia tau tias yog M=Nm / Vqhov twg M yog qhov sib nqus, N yog qhov ntau ntawm lub sijhawm sib nqus, m yog nws cov kev taw qhia thiab V yog qhov ntim ntawm cov qauv.
Yuav ua li cas yog cov qauv ntawm kev siv cov hlau nplaum?
Qhov kev siv ntawm magnetisation qhia txog qhov uas cov khoom yog magnetized. I=M V=m × 2 ℓ A × 2 ℓ=m A. Kev siv zog ntawm magnetisation kuj txhais tau tias yog lub zog ncej tsim los ntawm ib chav tsev ntawm ntu ntu ntawm cov qauv.
chav tsev magnetization yog dab tsi?
Net magnetization tshwm sim los ntawm cov lus teb ntawm cov khoom siv rau sab nraud magnetic teb. Lub zog ntawm ib tug ncej ntawm ib tug dipole yog hu ua ncej zog. Nws chav SI yog Ampere meter (Am). … Lub sij hawm sib nqus dipole tau txais ib chav tsev ntim yog hu ua Magnetization. Nws chav SI yuav yog Am2m=Am.
Puas yog qhov ntsuas ntawm magnetization?
Nws tuaj yeem muab piv rau hluav taws xob polarization, uas yog qhov ntsuas ntawm cov lus teb sib xws ntawm cov khoom siv rau hluav taws xob hauv electrostatics. Physicists thiab engineers feem ntau txhais magnetization li qhov kom muaj nuj nqis ntawm lub sij hawm sib nqus ib chav tsev ntim. Nws yog sawv cev los ntawm pseudoector M.
Yuav ntsuas li cas?
Remanence / residual magnetism
Remanence lossis residual magnetism yog qhov tshwj xeeb rau kev txiav txim siab ntawm lub zog hlau nplaum, qhov seem hlau nplaum lub zog tom qabcuam tshuam ntawm cov hlau nplaum los yog tom qab cov txheej txheem demagnetizing. Lub remanence tseem tuaj yeem ntsuas los ntawm ntsuas magnetic teb, gaussmeters thiab teslameters.
