Ntawm qhov one hand, cov ntaub ntawv ferrite tsuas them tus nqi ntawm cov ntaub ntawv NdFeB. Ntawm qhov tod tes, neodymium hlau nplaum muaj ib qho quab yuam uas muaj li 8 txog 10 npaug siab tshaj qhov uas zoo ib yam li ferrite magnet. Yog tias koj xam cov nqi ntawm ib lub luj ntawm cov quab yuam, ferrite magnets muaj li 2 rau 3 npaug dua li cov hlau nplaum neodymium. Qhov no yog qhov tseeb tshwj xeeb tshaj yog thaiv cov nplhaib lossis lub nplhaib ntau dua thiab rau ntau ntau. (Nrog cov nplua nuj hlau nplaum tus nqi ntawm ib lub luj ntawm cov quab yuam sib luag.)
Tus nqi kom zoo dua tsuas yog qhov tseem ceeb, tab sis, yog tias qhov nyhav thiab qhov loj me tsis txawv, vim hais tias ferrite cov hlau nplaum muaj ntau dua thiab loj dua li cov hlau nplaum neodymium nrog tib lub zog.
Nqe ruaj ntseg
Ferrite cov hlau nplaum tsis tshua muaj nqes zuj zus ntau dua li cov hlau nplaum neodymium vim tias lawv cov khoom tsis tsim kom tsis muaj cov hlau hauv ntiaj teb.
Kub siab
Ferrite magnets yuav siv tau los ntawm kub ntawm -40 ° C thiab 250 ° C, hos cov feem ntau cov neodymium hlau poob lawv qhov chaw txav ntawm qhov kub ntawm 80 ° C. Txawm li cas los xij, kub hauv -40 ° C tsis muaj teeb meem rau cov hlau nplaum neodymium.
