Qhov sib txawv tseem ceeb ntawm lub cev ntawm cov khoom sib nqus thiab cov hluav taws xob hluav taws xob yog raws li hauv qab no:
(1) Muaj cov khoom siv hluav taws xob zoo hauv qhov xwm txheej, thiab tseem muaj cov khoom siv insulating rau tam sim no. Piv txwv li, lub resistivity ntawm tooj liab yog 1.69 × 10-2Qmm2 / m, thaum lub resistivity ntawm roj hmab yog hais txog 10 npaug ntau dua. Tab sis txog tam sim no, tsis muaj cov ntaub ntawv insulated tiv thaiv magnetic flux tau pom. Qhov sib nqus permeability ntawm bismuth, uas muaj qhov tsawg tshaj plaws sib nqus permeability, yog 0. 99982μ . Qhov sib nqus permeability ntawm huab cua yog 1. 000038μ . Yog li ntawd, huab cua tuaj yeem pom raws li cov khoom siv nrog qis tshaj magnetic permeability. Tus txheeb ze permeability ntawm ferromagnetic cov ntaub ntawv nrog qhov zoo tshaj plaws permeability yog hais txog lub thib rau lub zog ntawm 10.
(2) Tam sim no yog qhov ntws ntawm cov khoom siv hluav taws xob hauv tus neeg xyuas pib. Vim muaj qhov muaj zog ntawm tus neeg xyuas pib, lub zog hluav taws xob electrodynamic ua haujlwm ntawm cov khoom siv hluav taws xob thiab siv lub zog, thiab lub zog poob tau hloov mus rau hauv tshav kub. Qhov sib nqus flux tsis sawv cev rau qhov kev txav ntawm ib qho loj, thiab nws tsis sawv cev rau lub zog poob, yog li qhov kev sib piv no yog treacherous. Lub voj voog thiab lub voj voog sib nqus zoo li sib cais, thiab txhua tus muaj nws tus kheej yam tsis xav nug txog kev hnia qhov laj thawj hauv cov pob. Qhov kev sib piv no yog ceg tawv vim qhov poob ntawm lub zog. Lub voj voog thiab lub voj voog sib nqus zoo li txawv, thiab txhua tus muaj nws tus kheej lub cev tsis sib xws.
Lub magnetic Circuit Court yog looser:
(1) Tsis muaj qhov tawg ntawm cov hlau nplaum ib yam li hauv Circuit Court; magnetic flux yog ubiquitous.
(3) Sib nqus circuits yuav luag ib txwm tsis yog linear. Cov tshuaj ferromagnetic magnetoresistance yog nonlinear, cov huab cua sib txawv magnetoresistance yog linear. Lub ohm txoj cai thiab kev tsis txaus siab tsis txaus siab ntawm cov kab hluav taws xob sib nqus tau teev tseg saum toj no yog qhov tseeb tsuas yog nyob rau hauv kab kab. Yog li qhov tsim tiag tiag, feem ntau siv BH nkhaus kom pom qhov ua haujlwm.
(2) Vim tias tsis muaj cov khoom siv tsis zoo, qhov sib nqus flux tsis muaj kev txwv, tsuas yog ib feem ntawm cov flux dhau los ntawm cov txheej txheem sib nqus, thiab cov seem yog tawg nyob rau hauv qhov chaw nyob ib ncig ntawm lub Circuit Court, uas yog hu ua to, thiab qhov tseeb xam thiab ntsuas ntawm qhov to yog qhov nyuaj, tab sis nws tsis tuaj yeem tsis quav ntsej.
