Cov khoom siv hlau nplaum yog dab tsi?

Cov hlau nplaum yog tsim los ntawm nias ferric oxide hmoov nrog muab tub lim thiab khi. Lub zog sib nqus ntawm cov hlau nplaum muaj qee yam kev sib raug zoo nrog cov ntsiab lus ntawm ferric oxide. Cov ntsiab lus ferric oxide ntau dua, qhov muaj zog ntawm cov hlau nplaum ntawm cov hlau nplaum. Hloov pauv, cov ntsiab lus ferric oxide tsawg dua, qhov tsis muaj zog ntawm cov hlau nplaum.
Kuv ntseeg tias ntau tus phooj ywg tsis paub ntau yam nrog cov hlau nplaum, thiab txawm tias me ntsis paub nrog lawv, tab sis qee cov phooj ywg yuav tsis meej meej txog cov khoom siv hlau nplaum yog ua los ntawm, yog li cia peb tshawb nrhiav ua ke.
Cov khoom siv raw los ua cov hlau nplaum
Cov hlau nplaum yog tsim los ntawm nias ferric oxide hmoov nrog muab tub lim thiab khi. Lub zog sib nqus ntawm magnetite muaj qee qhov kev sib raug zoo nrog cov ntsiab lus ntawm ferroferric oxide. Cov ntsiab lus ferric oxide ntau dua, qhov muaj zog ntawm cov hlau nplaum ntawm magnetite. Hloov pauv, cov ntsiab lus ferric oxide tsawg dua, qhov muaj zog ntawm cov hlau nplaum. qaug zog.
Taw qhia rau Magnet
Cov hlau nplaum tseem hu ua hlau nplaum, thiab lawv cov khoom yog hlau, cobalt, nickel thiab lwm yam atoms. Cov qauv sab hauv ntawm cov atoms yog qhov tshwj xeeb, thiab nws muaj lub sijhawm sib nqus nws tus kheej. Muaj ntau hom hlau nplaum, xws li cov hlau nplaum zoo li cov hlau nplaum: square hlau nplaum, pobzeb hlau nplaum, cov hlau nplaum tshwj xeeb zoo li cov hlau nplaum, cov hlau nplaum cylindrical, nplhaib hlau nplaum, disc hlau nplaum, cov hlau nplaum hlau nplaum, cov hlau nplaum hlau nplaum; Cov khoom siv hlau nplaum: samarium cobalt hlau nplaum, neodymium Hlau boron hlau nplaum (muaj zog hlau nplaum), ferrite hlau nplaum, alnico hlau nplaum, hlau chromium cobalt hlau nplaum; muaj cov hlau nplaum: cov khoom sib nqus, cov hlau nplaum lub cev muaj zog, cov hlau nplaum roj hmab, cov hlau nplaum yas, thiab lwm yam. Kuj tseem muaj ntau yam kev siv cov hlau nplaum, tshwj xeeb tshaj yog nyob rau hauv kev lag luam, xws li maglev tsheb ciav hlau thiab lwm yam.
