Dab tsi yog qhov txawv ntawm qhov sib nqus Circuit Court thiab cov yam ntxwv ntawm lub cev ntawm cov hlau nplaum muaj zog

Lub ntsiab sib txawv ntawm magnetic circuit thiab circuit lub cev muaj zog yog raws li nram no:
(1) Muaj cov khoom siv hluav taws xob zoo hauv qhov xwm txheej, thiab tseem muaj cov ntaub ntawv uas insulate tam sim no. Piv txwv li, qhov resistivity ntawm tooj liab yog 1.69 × 10-2qmm2 / m, thaum cov roj hmab yog li 10 npaug ntawm qhov ntawd. Tab sis txog tam sim no, tsis muaj cov ntaub ntawv tau pom los thaiv cov hlau nplaum sib nqus. Bismuth muaj qhov permeability qis tshaj plaws, uas yog 0. 99982μ. Lub permeability ntawm huab cua yog 1.000038 μ. Yog li huab cua tuaj yeem suav tias yog cov khoom siv nrog qhov qis tshaj permeability. Qhov zoo tshaj plaws ferromagnetic cov ntaub ntawv muaj txheeb ze permeability ntawm 10 mus rau lub thib rau lub zog.

(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 ua haujlwm ntawm cov khoom siv hluav taws xob thiab siv lub zog, thiab lub zog poob tau hloov mus rau hauv lub zog hluav taws xob. Qhov sib nqus flux tsis sawv cev rau kev txav ntawm ib qho twg, thiab nws tsis sawv cev rau qhov poob ntawm lub zog, yog li qhov kev sib piv no tsis tsim nyog. Cov hluav taws xob hluav taws xob thiab hluav taws xob sib nqus yog qhov sib txawv heev, txhua tus muaj nws tus kheej hauv pob. Poob, yog li qhov piv txwv yog ceg tawv. Circuit Court thiab magnetic Circuit Court yog sib cais, txhua tus muaj nws tus kheej unquestioned lub cev connotation.

Magnetic circuits yog looser:
(1) Yuav tsis muaj kev cuam tshuam hauv Circuit Court, sib nqus flux nyob txhua qhov chaw.
(3) Sib nqus circuits yuav luag ib txwm tsis muaj kab. Ferromagnetic cov khoom tsis kam yog nonlinear, huab cua sib txawv tsis kam yog linear. Qhov sib nqus Circuit Court ohm txoj cai lij choj thiab cov ntsiab lus tsis txaus siab uas tau teev tseg saum toj no tsuas yog muaj tseeb hauv cov kab tawm. Yog li ntawd, nyob rau hauv kev tsim qauv, bH nkhaus feem ntau yog siv los xam qhov chaw ua hauj lwm.
(2) Vim tias tsis muaj cov khoom siv hlau nplaum kiag li, qhov sib nqus flux yog unconstrained. Tsuas yog ib feem ntawm qhov sib nqus flux ntws los ntawm cov txheej txheem sib nqus, thiab qhov seem yog tawg mus rau hauv qhov chaw nyob ib ncig ntawm lub voj voog sib nqus, uas yog hu ua magnetic to. Qhov tseeb xam thiab ntsuas ntawm qhov sib nqus flux to no nyuaj, tab sis tsis tuaj yeem tsis quav ntsej.
