Kuv tsis muaj los yog µ0 yog qhov permeability tas li yog synonymous rau permeability ntawm qhov chaw dawb los yog li Sib nqus tas li. Kuv tsis muaj tus nqi yog qhov ntsuas ntawm tus nqi ntawm kev tiv thaiv tawm tsam kev tsim ntawm lub magnetic teb hauv lub tshuab nqus tsev.

Ntawm no, MU yog dab tsi hauv magnetic teb?

Sib nqus permeability. Sib nqus permeability Μ (Greek mu ) yog li txhais tau tias Μ = B/H. Sib nqus flux density B yog qhov ntsuas ntawm qhov tseeb magnetic teb nyob rau hauv ib yam khoom uas xam tau tias yog ib tug concentration ntawm magnetic teb kab, los yog flux, nyob rau hauv ib cheeb tsam cross-sectional.

Ib yam li ntawd, tus nqi ntawm u0 yog dab tsi? Lub permeability ntawm qhov chaw dawb, Μ0, yog lub cev tas li siv feem ntau hauv electromagnetism. Nws txhais tau tias muaj qhov tseeb tus nqi np4x 10-7 N/A2 (Newtons ib ampere squared).

Ib yam li ntawd, dab tsi yog MU tsis nyob hauv Ampere txoj cai?

Ampere Txoj Cai , tshwj xeeb tshaj yog hais tias lub magnetic teb tsim los ntawm ib tug hluav taws xob tam sim no proportional rau qhov luaj li cas ntawm cov hluav taws xob tam sim no nrog ib tug tas li ntawm proportionality sib npaug zos rau permeability ntawm qhov chaw dawb. Mu -zero yog qhov permeability ntawm qhov chaw dawb, uas yog qhov tsis tu ncua uas ib txwm sib npaug rau 1.257 x 10^-6.

Cov mis ntawm magnetic teb yog dab tsi?

Ib txoj hlua nqa tam sim no xav tias muaj zog nyob rau hauv lub xub ntiag ntawm sab nraud magnetic teb . Nws pom tau tias yog F = Bilsinθ F = Bi l sin θ, qhov twg ℓ yog qhov ntev ntawm cov hlau, kuv yog tam sim no, thiab θ yog lub kaum sab xis ntawm qhov kev taw qhia tam sim no thiab magnetic teb.
