    Txhim Kho Cov Hlau nplaum Ntau Lawm

    Ntau cov txuj ci thev naus laus zis tsuas yog ua tau tom qab kev txhim kho ntawm cov hlau nplaum ruaj khov tsis tu ncua hauv ntau yam duab thiab ntau thiab tsawg. Niaj hnub no, cov ntaub ntawv sib nqus muaj cov sib nqus sib txawv thiab lub zog sib txawv, thiab plaub tsev neeg ntawm cov hlau nplaum tas mus li tuaj yeem siv rau hauv ntau hom kev siv.

    RUMOTEK hlau nplaum muaj ntau cov khoom loj ntawm cov hlau nplaum ruaj khov nyob rau hauv ntau cov duab thiab ntau thiab tsawg uas sib txawv nrog cov neeg siv daim ntawv thov, thiab tseem muaj cov hlau nplaum uas siv tau. Ua tsaug rau peb cov kev txawj ntse hauv kev ua cov khoom sib nqus thiab cov hlau nplaum ruaj khov, peb tau tsim ntau yam kev sib nqus ntawm cov khoom sib nqus rau kev siv.

    Dab tsi yog qhov txhais ntawm cov hlau nplaum?
    Cov hlau nplaum yog ib yam khoom uas muaj peev xwm tsim qhov chaw sib nqus. Tag nrho cov hlau nplaum yuav tsum muaj tsawg kawg ib North Ncej, thiab ib qho South South Ncej.

    Dab tsi yog qhov sib nqus?
    Lub tshav pob sib nqus yog thaj chaw ntawm qhov chaw uas muaj kev kuaj pom pom lub zog sib nqus. Lub zog nqus muaj qhov ntsuas lub zog thiab qhov taw qhia.

    Dab tsi yog hlau nplaum?
    Hlau nplaum yog hais txog lub zog quab yuam los yog rov ua kom tshwm sim nruab nrab ntawm cov tshuaj ua los ntawm cov khoom siv tshwj xeeb xws li hlau, nickel, cobalt thiab hlau. Qhov kev quab yuam no tshwm sim vim los ntawm cov lus txav ntawm cov nqi hluav taws xob nyob hauv kev lag luam atomic qauv ntawm cov khoom siv no.

    Dab tsi yog qhov hlau nplaum "mus tas li"? Qhov ntawd txawv ntawm "elecromagnet" li cas?
    Cov hlau nplaum tas mus li tseem txuas ntxiv emit sib nqus txawm tias tsis muaj lub zog siv hluav taws xob, whereas ib qho xaim hluav taws xob yuav tsum muaj lub zog hluav taws xob txhawm rau tsim cov khoom sib nqus.

    Dab tsi yog qhov sib txawv isotropic thiab anisotropic magnet?
    Ib lub isotropic hlau nplaum tsis yog taw qhia thaum lub sijhawm kev tsim khoom, thiab yog li ntawd tuaj yeem muab cov hlau nplaum hauv txhua qhov kev coj tom qab nws tau tsim. Hauv kev sib piv, anisotropic magnet yog raug rau lub zog sib nqus thaum lub sij hawm tsim khoom siv los txhawm rau txhawm rau tso cov khoom sib dhos hauv qhov kev taw qhia tshwj xeeb. Raws li qhov tshwm sim, anisotropic hlau nplaum tsuas tuaj yeem raug txhawb nqa nyob rau hauv ib qho kev taw qhia; txawm li cas los lawv feem ntau muaj cov khoom sib nqus muaj zog.

    Dab tsi txhais tau cov hlau nplaum polarity?
    Yog tias tso cai txav mus los dawb, lub hlau nplaum yuav ua kom sib npaug nrog sab qaum teb-sab qab teb polarity ntawm lub ntiaj teb. Tus ncej uas nrhiav sab qab teb yog hu ua "South ncej" thiab tus ncej uas taw tes rau sab qaum teb yog hu ua "North pole."

    Lub hlau nplaum lub zog ntsuas li cas?
    Kev sib nqus muaj zog yog ntsuas hauv ob peb txoj kev sib txawv. Nov yog qee qhov piv txwv:
         1) Ib qhov Gauss Meter siv los ntsuas lub zog ntawm daim teb muaj hlau nplaum tawm hauv cov khoom hu ua "gauss."
         2) Cov Kuaj Cov Hluav Taws Xob tuaj yeem siv los ntsuas qhov hnyav uas cov hlau nplaum tuaj yeem tuav hauv phaus lossis phaus.
         3) Cov Tso Cai Siv tau siv los txheeb xyuas lub caij nyoog sib nqus cov yam ntxwv ntawm cov khoom siv tshwj xeeb.
