Magnetic permeability, txheeb ze nce lossis txo qhov tshwm sim hauv cov khoom sib nqus hauv cov khoom piv nrog cov hlau nplaumnyob rau hauv cov khoom muab nyob rau hauv; los yog cov cuab yeej ntawm ib yam khoom uas sib npaug zos sib nqus flux density B tsim nyob rau hauv cov khoom los ntawm ib tug magnetizing teb muab faib los ntawm …
Magnetic permeability yog dab tsi?
Sib nqus permeability txhais tau tias qhov piv ntawm qhov sib nqus induction rau qhov sib nqus siv. Nws yog ib tug scalar ntau thiab denoted los ntawm lub cim μ. Sib nqus permeability pab peb ntsuas cov khoom tiv thaiv rau lub magnetic teb los yog ntsuas qhov degree uas magnetic teb tuaj yeem nkag mus los ntawm cov khoom.
txhais li cas permeability?
Permeability yog qhov zoo lossis lub xeev ntawm permeable -muaj peev xwm nkag mus lossis dhau mus, tshwj xeeb tshaj yog los ntawm cov kua lossis roj. Cov lus qhia permeate txhais tau tias nkag mus, dhau mus, thiab feem ntau dhau mus thoob plaws ib yam.
Yuav ua li cas xam magnetic permeability?
Magnetic permeability yog sawv cev li μ (nws yog pronounced li mu) thiab qhia tau tias yog μ=B/H, qhov twg, B yog qhov sib nqus flux ntom uas yog Kev ntsuas ntawm qhov tseeb magnetic teb nyob rau hauv ib cov khoom thiab yog xam raws li ib tug concentration ntawm magnetic teb kab los yog magnetic flux ib chav tsev cross-sectional cheeb tsam.
txhais li cas los ntawm permeability ntawm cov khoom?
Permeability yog ibntsuas qhov yooj yim sib nqus kab ntawm lub zog tuaj yeem dhau los ntawm cov khoom siv. Lub permeability ntawm cov khoom yog txhais raws li qhov tas li ntawm proportionality ntawm magnetic flux ceev thiab magnetic teb.
