Hlau nplaum txhais cov ntsiab lus
Ib tug varistor yog magnetically rhiab, magnetoresistive resistor caij. Qhov tshwm sim uas qhov tawm tsam ntawm cov khoom hloov pauv hauv qhov chaw sib nqus tau yog hu ua cov txiaj ntsig magnetoresistance. Tus varistor feem ntau yog ua los ntawm cov khoom siv hluav taws xob (semiconductor material) rhiab rau cov khoom sib nqus xws li indium bromide (InSb) lossis indium arsenide (InAs). Cov txiaj ntsig magnetoresistance ntawm cov khoom siv sib xyaw ua ke muaj xws li lub cev cov hlau nplaum ua kom muaj lub zog thiab cov duab hluav taws xob tiv thaiv cov duab hluav taws xob, uas tseem hu ua magnetoresistance effect.
