Cov hlau ntshiab muaj qhov tseem ceeb ua cov khoom siv sib nqus. Nws cov siab siab sib nqus sib nqus kev siv txhais tau tias yog cov hlau sib nqus tuaj yeem khaws cov khoom sib nqus tib yam uas xav tau cov chaw sib nqus thiab muaj zog sib nqus. Tsis tas li ntawd, ntshiab hlau ntshiab muaj cov hlau nplaum zoo heev permeability, uas ua rau nws teb sai sai rau kev hloov pauv ntawm kev sib nqus thiab txo cov kev poob siab. Qhov tseem ceeb tshaj, qhov kev ua kom qis dua thiab muaj peev xwm ua tau zoo thiab ruaj khov rau kev txhim kho cov khoom siv sib nqus thiab nthuav dav lub neej.
Txawm hais tias Silicon steel muaj qhov zoo hauv qee yam xws li txo cov hlau loj tam sim no, thiab qis hysteres me me ua rau nws muaj kev xaiv zoo tshaj plaws hauv cov ntawv thov kev thov. Tshwj xeeb tshaj yog rau cov ntawv thov uas xav tau kev ua tau zoo, thiab tsis nkag siab txog tus nqi, cov hlau ntshiab yog qhov ua tau zoo sib nqus cov khoom muaj nqis.
