Kev faib cov khoom sib nqus

Cov khoom sib nqus tau muab faib ua ob pawg: hlau thiab tsis yog-hlau raws li lawv cov khoom. Cov qub feem ntau suav nrog cov hlau hluav taws xob, npib tsib xee-raws li alloys thiab tsis tshua muaj ntiaj teb alloys, thiab tom kawg yog cov khoom siv ferrite. Raws li kev siv, nws tau muab faib ua cov khoom sib nqus mos, cov khoom sib nqus ruaj khov thiab cov khoom siv hlau nplaum ua haujlwm. Cov khoom siv hlau nplaum ua haujlwm feem ntau suav nrog cov ntaub ntawv magnetostrictive, cov ntaub ntawv sib nqus, cov ntaub ntawv magnetoresistive, cov ntaub ntawv sib nqus npuas, magneto- cov ntaub ntawv kho qhov muag, cov ntaub ntawv gyromagnetic thiab cov khoom siv magnetic, thiab lwm yam. hysteresis lub voj voog. thiab magnetic poob, thiab lwm yam.
