Intrinsic magnetic zog ntawm cov hlau nplaum ruaj khov uas suav nrog remanence Br, coercivity Hcb, intrinsic coercivity Hcj, thiab Max. Cov Khoom Siv Hluav Taws Xob (BH) max, feem ntau yog nyob ntawm nws qhov muaj pes tsawg leeg thiab microstructure, ces tsis muaj dab tsi ua nrog cov duab thiab qhov ntev. Txawm li cas los xij, cov kev sib nqus sib nqus uas ib txhij cuam tshuam los ntawm cov duab thiab qhov ntev, suav nrog tus nqi gauss, sib nqus flux lossis lub sijhawm sib nqus, tau txais kev saib xyuas ntau dua los ntawm cov neeg siv.
Lub sijhawm sib nqus ntawm cov hlau nplaum ruaj khov yog kuaj los ntawm Helmholtz coil thiab Fluxmeter. Nws tus nqi muaj feem xyuam rau remanence Br, qhov ntev, thiab Pc tus nqi ntawm cov hlau nplaum. Sib nqus flux thiab sib nqus lub sijhawm tuaj yeem hloov pauv mus rau ib leeg ntawm cov coil tas li, yog li tsim nyog rau kev sib nqus kev sib piv ntawm cov hlau nplaum manufacturers thiab cov neeg siv.
Qhov loj me thiab cov duab ntawm cov hlau nplaum ruaj khov tau me dua thiab nyuaj, feem ntau, tshwj xeeb tshaj yog cov hlau nplaum uas muaj zog sintered Neodymium hlau nplaum rau cov neeg siv khoom siv hluav taws xob. Yog li ntawd, nws yog qhov nyuaj heev los sim lawv cov kev ua tau zoo ntawm Gaussmeter thiab Fluxmeter, tom qab ntawd lub sijhawm sib nqus tau raug kho raws li qhov kev xaiv tsim nyog los sau cov nqi raug nrog kev rov ua tau zoo dua. Rau cov hlau nplaum ruaj khov nrog ncaj BH nkhaus, lawv lwm yam sib nqus tsis xws li kev khiav hauj lwm flux ceev Bd, kev khiav hauj lwm lub zog Hd, coercivity Hcb, remanence Br, thiab Max. Cov Khoom Siv Hluav Taws Xob (BH) max yog txhua yam tuaj yeem kwv yees tau los ntawm kev ntsuas lub sijhawm sib nqus. Txawm tias muaj feem cuam tshuam txoj kev txiav tawm tsis yog qhov tseeb raws li kev ntsuas hysteresisgraph thiab tsis tuaj yeem muab qhov kev sib koom ua ke Hcj, nws cov txheej txheem ntsuas thiab txiav tawm yog qhov yooj yim thiab cov khoom siv tus nqi tsawg dua. Tsis tas li ntawd, nws qhov kev ntsuas kev ua tau zoo yog zoo tshaj hysteresisgraph, tom qab ntawd zoo yoog rau 100% kev tshuaj xyuas.
