Cov hlau nplaum ntawm cov hlau nplaum khov yog haib heev. Txhua tus yuav tsum paub tias, tshwj xeeb tshaj yog cov hlau nplaum muaj zog loj, vim tias lawv lub zog loj heev, lawv tau yooj yim ua rau tib neeg thaum lawv siv. Yog li yuav ua li cas demagnetize lub zog loj hlau nplaum?
Txoj kev degaussing ntawm cov hlau nplaum muaj zog yog qhov yooj yim heev, vim tias qhov ntsuas kub ntawm qhov muaj zog ntawm cov hlau nplaum uas muaj zog yog qis dua 80 degrees, peb tsuas yog muab tso rau ntawm hluav taws rau ob peb feeb thiab tom qab ntawd txias nws cia. Lub sijhawm no, yog tias nws tso tso rau ib sab ntawm cov hlau, nws yuav poob nws cov ntawv hlau nplaum thiab tsis tuaj yeem tuav cov hlau thaiv. Qhov laj thawj yog vim li cas cov kev cai tswj ntawm cov hlau atoms hauv cov hlau nplaum muaj zog yog cuam tshuam los ntawm cua kub, yog li poob qhov qub cov hlau nplaum. Ib yam li ntawd, lwm txoj hauv kev tuaj yeem siv los rhuav tshem cov hlau nplaum uas muaj zog.
Qhov saum toj no yog hais txog txoj kev demagnetization ntawm tus hlau nplaum haib, Kuv vam tias nws yuav pab tau koj.
