Raws li peb txhua tus paub, tus N ntawm NdFeB yog poob ntawm kev sib nqus quab yuam ntau tshaj 80 degrees. Tab sis ua li cas yog tias cov ntawv hlau muab tso rau hauv qhov hluav taws kub thiab neodymium hlau boron muab tso rau hauv nws, thiab neodymium hlau taws kub hlawv hauv qhov cub?
Cov hlau nplaum yuav hlawv thiab hlawv thaum nws kub hnyiab, vim hais tias cov hlau nplaum tau tawg thiab txawm tias kub nyhiab, tiam sis qhov taw tes yaj thiab cov tiv thaiv taw tiv thaiv yog siab heev. (SM Co, Al Ni Co, thiab lwm yam.
Kev kub siab yuav pauv cov qauv ntawm cov hlau nplaum molecular, thiab cov hlau nplaum yuav tsis muaj zog lossis txawm tias yuav muaj hlau nplaum tom qab cov kub ntxhov siab. Qhov no yog pom tsis pom qhov muag liab qab. Ntawm chav kawm, yog tias peb cia li flashed los ntawm cov nplaim taws, qhov kub tsis hloov hauv ntau. (feem ntau ntawm cov hlau nplaum, feem ntau, cov hlau nplaum uas kub hauv qab 80 degrees thiaj li muaj peev xwm tiv thaiv. Cov hlau nplaum ntawm cov khoom sib txawv nyias txawv nyias li, xws li 80 ~ 400 degrees.
Thaum cov hlau nplaum thiab cov hlau nplaum nce lawm, cov nqi hluav taws xob hauv lub tshuab muaj zog ntawm lub cev yog ntau zog dua ua ntej, yog li sib nqus siv dag zog thiab cov txheej txheem molecular mob nyhav, uas cuam tshuam cov qauv ntawm kev cai qub , thiab lub cev molecular kub zog yog tau ceev dua thiab sai dua. Yog li, ntau ntau thiab ntau hauv xov tooj yuav tsis mloog cov lus "password" ntawm "queuing". Tom qab txias, cov hlau nplaum tseem rov tau ib feem ntawm kev sib nqus sib nqus.
Thaum twg qhov kub nce mus rau ib qho nqi, lub zog molecular heat zog thaum kawg kiag li qhov ua raws li kev coj ua ntawm cov lus tsa suab hluav taws xob, thiab qhov magnetism ntawm cov hlau nplaum ploj. Qhov kub ntawm cov hlau nplaum thiab cov hlau nplaum tas lawm ploj los ntawm cov hlau nplaum yog hu ua "Curie temperature". Lub Curie kub ntawm hlau thiab hlau yog 770 degree C.
Qee qhov tsim cov qauv tsim tau yeej tau rov qab, xws li cov hlau nplaum nyob hauv nruab nrab ntawm lub tshuab raj cookies. Txoj kev ntawm degaussing yog los muab cov khoom sib txig sib txig sib txig ua ib qho kev sib zog ua kom muaj magnetic field thiab maj mam txo nws mus xoom. Lub degaussing kauj siv nyob rau hauv lub neej tiag tiag tapes thiab televisions yog tus qauv siv.
