Neodymium hlau nplaum yuav demagnetized ntawm qhov kub thiab txias, nyob ntawm lawv lub cev qauv. Cov hlau nplaum zoo tib yam tsim cov hlau nplaum vim tias cov khoom siv hluav taws xob nqa los ntawm lawv tus kheej tig ib ncig ntawm cov atoms hauv ib qho kev taw qhia, tsim kom muaj lub zog sib nqus uas cuam tshuam rau txhua yam nyob ib puag ncig lawv. Txawm li cas los xij, cov electrons nyob ib ncig ntawm lub atom kuj muaj qee qhov kub thiab txias raws li cov lus qhia, thiab cov khoom sib nqus sib txawv tuaj yeem tiv taus qhov kub thiab txias. Nyob rau hauv cov ntaub ntawv ntawm kub dhau heev lawm, cov electrons yuav deviate los ntawm tus thawj khiav, ua rau chaos, thiab lub zos magnetic teb ntawm magnetic cov ntaub ntawv yuav cuam tshuam thiab degaussed.
Qhov kub ua haujlwm siab tshaj plaws ntawm NdFeB cov khoom sib nqus yog li 220 degrees, ntau dua 200 degrees yuav tshwm sim demagnetization tshwm sim, qhov kub siab dua, qhov tshwm sim loj dua qhov demagnetization tshwm sim.
NdFeB hlau nplaum siab kub demagnetization tov:
1. Ua tib zoo saib xyuas kev siv ib puag ncig, tsis txhob muab cov khoom siv hlau nplaum neodymium nyob rau hauv qhov chaw ua haujlwm kub. Lub ambient kub yuav tsum tsis txhob ntau tshaj 200 degrees, thiab yuav tsum tau qis tshaj qhov tseem ceeb point ntawm nws ua hauj lwm kub.
2. Los ntawm kev pom zoo, txhim kho cov khoom ua tau zoo ntawm kev siv NdFeB cov hlau nplaum ruaj khov, kom nws tuaj yeem muaj cov qauv kub ntau dua, tsis yooj yim rau kev cuam tshuam los ntawm ib puag ncig.
3. Koj tuaj yeem xaiv cov khoom siv hluav taws xob sib nqus zoo tib yam nrog kev ua haujlwm siab.
