Qhov sib nqus permeability ntawm electromagnetic ntshiab hlau yog li ntawm 200 mus rau 600, uas txhais tau hais tias nyob rau hauv tib lub zog hlau nplaum, qhov sib nqus induction siv hauv electromagnetic ntshiab hlau yog ntau pua zaus hauv lub tshuab nqus tsev. Tsis tas li ntawd, qhov sib nqus permeability ntawm electromagnetic ntshiab hlau tseem cuam tshuam los ntawm nws cov ntsiab lus purity thiab impurity. Piv txwv li, lub purity ntawm electromagnetic ntshiab hlau muaj peev xwm ncav cuag 99.8% mus rau 99.9%, nrog siab saturation magnetic induction siv, tsawg coercive quab yuam, thiab ib tug siab tshaj plaws magnetic permeability ntawm 6.25 mus 12.50mH / m.
