Ob qho tib si feem ntau siv hauv cov twj sib nqus. Cov hlau nplaum tsis muaj zog tseem hu ua ferrite hlau nplaum, thiab cov hlau nplaum muaj zog hu ua NdFeB hlau nplaum.
Ua ntej tshaj plaws, cia kuv qhia ferrite, uas yog ib hom hlau nplaum dub, uas yog dav siv hauv pob ntseg, hais lus, cov hlau nplaum ruaj khov thiab lwm yam, thiab tau kawg peb lub twj tso kua mis sib nqus. Cov khoom siv hlau nplaum saum npoo av (tus nqi ntawm cov khoom sib nqus siab thiab qis) ntawm cov hlau nplaum ferrite feem ntau tuaj yeem ncav cuag 12000-16000Gs tom qab saturation magnetization. Lub theoretical kub tsis kam yog 250 degree, cov hlau nplaum yuav demagnetize nyob rau hauv ib tug nkhaus ntawm qhov kub thiab txias, thiab cov hlau nplaum yuav rov qab tag nrho thaum qhov kub thiab txias. Piv nrog rau lwm yam khoom siv hlau nplaum, tus nqi muaj qhov zoo dua, tab sis vim qhov kev txwv ntawm cov khoom siv hluav taws xob sib nqus, nws tsis tuaj yeem siv rau hauv ntau qhov kev lag luam. Yog li ntawd, lub twj tso kua mis sib nqus ua los ntawm ferrite magnetic steel muaj qhov zoo ntawm tus nqi piv nrog lub zog sib nqus sib nqus twj tso kua mis, tab sis nws tsis muaj peev xwm thaum thauj cov xov xwm high-density. Thiab vim qhov kev txwv ntawm qhov nkhaus demagnetization cov yam ntxwv ntawm cov hlau nplaum, cov hlau nplaum yuav ploj zuj zus ntxiv tom qab tshaj 100 degree, thiab qhov tshwm sim ntawm sab hauv thiab sab nraud sib nqus sib nqus yog qhov tshwm sim. Yog li ntawd, qhov kub thiab txias teb kuj tseem txwv.
