Lub permittivity ntsuas qhov cuam tshuam tsim los ntawm cov khoom tsimntawm hluav taws xob teb, whereas lub permeability yog lub peev xwm ntawm cov khoom tso cai rau magnetic kab los ntawm nws. … Lub permittivity tsim lub teb hluav taws xob, whereas lub permeability tsim lub magnetic teb.
Dab tsi yog cov khoom ntawm permeability thiab permittivity?
Yog li, cov khoom ntawm permeability ntawm qhov chaw dawb thiab permittivity yog 1/c^2.
Dab tsi yog hu ua permittivity?
Nyob hauv electromagnetism, qhov kev tso cai tsis raug, feem ntau hu ua permittivity thiab denoted los ntawm Greek tsab ntawv ε (epsilon), yog ib qho kev ntsuas ntawm hluav taws xob polarizability ntawm ib dielectric. … Qhov no dimensionless ntau kuj yog feem ntau thiab ambiguously xa mus rau raws li permittivity.
kev tso cai ntawm cov khoom yog dab tsi?
: lub peev xwm ntawm cov khoom siv los khaws cov hluav taws xob muaj peev xwm nyob rau hauv kev cuam tshuam ntawm qhov hluav taws xob ntsuas los ntawm qhov sib piv ntawm lub peev xwm ntawm lub capacitor nrog cov khoom siv raws li dielectric rau nws cov capacitance nrognqus raws li dielectric.
Kev sib raug zoo ntawm kev tso cai ntawm qhov chaw dawb permeability thiab ceev ntawm lub teeb yog dab tsi?
Lub teeb nrawm yog cuam tshuam nrog hluav taws xob permittivity ntawm qhov chaw dawb εo thiab sib nqus permeability ntawm qhov chaw dawb μo.
