Qhov Tseem Ceeb Qhov txawv - Sib nqus Permeability vs Susceptibility
Sib nqus permeability thiab susceptibility yog qhov ntsuas ntau ntawm cov khoom sib nqus ntawm cov khoom. Qhov sib txawv tseem ceeb ntawm magnetic permeability thiab susceptibility yog tias magnetic permeability piav qhia txog lub peev xwm ntawm cov khoom siv los txhawb kev tsim cov hlau nplaum hauv nws tus kheej thaum susceptibility piav qhia seb cov khoom puas nyiam rau hauv magnetic teb los yog repelled los ntawm nws. Sib nqus susceptibility yog ib qhov dimensionless ntsuas.
Magnetic Permeability yog dab tsi?
Sib nqus permeability ntawm cov khoom yog lub peev xwm ntawm cov khoom siv los txhawb kev tsim cov hlau nplaum hauv nws tus kheej. Yog li ntawd, nws tseem hu ua qib ntawm magnetization (cov lus teb rau sab nraud magnetic teb). Qhov sib nqus permeability yog txhais los ntawm "μ". Chav tsev SI rau qhov sawv cev ntawm kev sib nqus permeability yog Henries ib 'meter' (H / m lossis H·m−1). Chav tsev no sib npaug rau Newtons ib ampere squared (N·A−2).
Qhov sib nqus permeability yog qhov ntsuas txheeb ze uas raug coj los ntawm kev sib nqus permeability ntawm lub tshuab nqus tsev. Qhov sib nqus permeability ntawm lub tshuab nqus tsev yog lub npe hu ua magnetic permeability tas li thiab yog txhais los ntawm "μ 0 ". Nws yog ib qho kev ntsuas ntawm qhov tsis kam pom nyob rau hauv lub tshuab nqus tsev thaum tsim ib qho chaw sib nqus hauv lub tshuab nqus tsev. Tus nqi ntawm qhov tsis tu ncua yog 4π × 10−7 H·m−1
Daim duab 1: Sib nqus permeability hauv cov khoom sib txawv
Cov khoom sib txawv muaj qhov sib txawv rau lawv qhov sib nqus permeability. Piv txwv li, cov khoom siv diamagnetic muaj qhov txheeb ze sib nqus permeability tsawg dua 1 thaum cov khoom siv paramagnetic muaj nqi me ntsis siab dua 1. Qhov no txhais tau tias thaum cov khoom siv paramagnetic muab tso rau hauv qhov cuam tshuam ntawm sab nraud magnetic teb, nws dhau los ua cov hlau nplaum me ntsis (rau ib qho kev taw qhia ib yam li nyob rau hauv sab nraud magnetic teb). Tab sis cov ntaub ntawv ferromagnetic tsis muaj txheeb ze permeability.
Magnetic Susceptibility yog dab tsi?
Magnetic susceptibility yog qhov ntsuas ntawm cov khoom sib nqus ntawm cov khoom siv uas qhia tias cov khoom puas tau txais los yog tawm ntawm qhov chaw sib nqus sab nraud. Qhov no yog qhov ntsuas qhov ntau ntawm cov khoom sib nqus.
Cov khoom sib txawv muaj qhov sib txawv rau qhov sib nqus nqus. Cov ntaub ntawv paramagnetic muaj qhov sib nqus nqus ntau dua li xoom thaum cov ntaub ntawv diamagnetic muaj nqi tsawg dua xoom. Qhov no txhais tau hais tias cov ntaub ntawv diamagnetic zoo li yuav raug tshem tawm los ntawm qhov chaw sib nqus thaum cov khoom siv paramagnetic yog nyiam mus rau qhov chaw sib nqus. Qhov sib nqus susceptibility ntawm cov khoom yog muab los ntawm kev sib raug zoo hauv qab no.
M=Xm. H
M yog lub sijhawm sib nqus ntawm ib chav tsev ntim ntawm cov khoom thiab H yog qhov siv ntawm sab nraud magnetic teb. Xm qhia tias muaj kev cuam tshuam sib nqus.

Summary – Sib nqus Permeability vs Susceptibility
Sib nqus permeability yog muab los ntawm cov units Henries ib 'meter', thiab magnetic susceptibility yog ib tug dimensionless khoom ntawm cov ntaub ntawv. Qhov sib txawv tseem ceeb ntawm kev sib nqus permeability thiab susceptibility yog qhov sib nqus permeability piav qhia txog lub peev xwm ntawm cov khoom siv los txhawb kev tsim cov magnetic teb hauv nws tus kheej thaum susceptibility piav qhia seb cov khoom puas tau nyiam rau hauv magnetic teb los yog repelled los ntawm nws.
