Ntau tus neeg muas zaub feem ntau ntsib teeb meem ntawm kev xaiv coil thaum xaiv lub fluxmeter los ntsuas cov khoom sib nqus. Vim tias lub fluxmeter tsuas tuaj yeem ntsuas qhov sib nqus flux ntawm cov hlau nplaum nrog lub kauj. Cov coils yuav yog monolithic coils, tsau B coils lossis Helmholtz coils.
1. Raws li rau ib kauj ruam, koj tuaj yeem cua nws ntawm tus qauv koj tus kheej, lossis koj tuaj yeem ua lub tes tsho loj dua li cov qauv, muab cov qauv tso rau hauv thiab rub tawm rau kev sim.
2. Lub kauj B ruaj khov yog siv rau kev sim, ib qho kev sim coil rau txhua tus qauv loj.
3. Helmholtz coils tuaj yeem siv rau kev sim. Helmholtz coils tuaj yeem siv los ntsuas ntau qhov ntau thiab tsawg ntawm cov qauv (qhov no xav kom cov neeg siv khoom muab qhov tsawg kawg nkaus thiab siab tshaj tus qauv loj).
Fluxmeters uas ntsuas nrog Helmholtz coils feem ntau yog siv ntau dua.
Vim hais tias thaum siv lub fluxmeter ( rooj), cov hlau nplaum ruaj khov feem ntau yog siv los "muab txoj hauv kev", thiab cov hlau nplaum ntawm cov qauv muaj feem xyuam nrog cov hlau nplaum sib nqus ntawm cov txheej txheem ntawm cov coils. Txoj kev no yog qhov yooj yim thiab siv tau rau txhua tus qauv ntawm cov qauv sib txawv, tab sis muaj qhov tsis zoo Nws yog qhov yuav tsum tau siv cov coils ntawm ntau qhov sib txawv thiab nruj me ntsis siv cov qauv nyias. Kev npaj ntawm kev tshawb nrhiav coils yog qhov nyuaj, teeb meem thiab tsis muaj txiaj ntsig. Txawm li cas los xij, ntsuas qhov sib nqus flux nrog Helmholtz coils tuaj yeem daws cov teeb meem saum toj no rau qee qhov, yog li ntsuas qhov sib nqus flux nrog Helmholtz coils hauv ib qho sib nqus flux yog txoj hauv kev zoo tshaj plaws.
