Cov kws tshawb fawb tau ua cov kev sim siv ib txoj hauv kev ntsuas hluav taws xob conductivity hu ua "Hall effect", thiab pom tias cov ntaub ntawv tooj liab yog 10% siab dua li yav tas los ntseeg.
Qhov kev tshawb pom no tseem ceeb heev vim tias cov ntawv tooj liab tau siv ntau yam kev siv, suav nrog cov khoom siv hluav taws xob thiab hluav taws xob. Kev siv hluav taws xob siab dua txhais tau tias cov ntawv tooj liab tuaj yeem nqa hluav taws xob ntau dua los ntawm lawv, uas tuaj yeem txhim kho cov khoom siv hluav taws xob thiab txo cov hluav taws xob poob hauv cov phiaj hluav taws xob.
Cov kws tshawb fawb kuj pom tau tias qhov conductivity ntawm cov nplooj ntawv tooj liab yog qhov rhiab heev rau purity ntawm cov khoom. Purer tooj liab ntawv muaj cov conductivity siab dua li cov ntshiab ntshiab. Qhov kev tshawb pom no tuaj yeem siv tau los ua cov khoom siv hluav taws xob zoo heev rau kev siv hluav taws xob thiab lwm yam haujlwm.
Hauv cov ntsiab lus, txoj kev tshawb no tau qhia tias cov ntawv tooj liab muaj hluav taws xob ntau dua li qhov kev xav yav dhau los, uas tuaj yeem cuam tshuam rau ntau yam kev lag luam thiab kev siv thev naus laus zis.
