Cov khoom siv ferromagnetic
Cov khoom siv ferromagnetic yog hais txog cov khoom uas muaj ferromagnetic zog. Piv txwv li, hlau, cobalt, npib tsib xee thiab lawv cov alloys, alloys thiab cov tebchaw ntawm qee lub ntiaj teb tsis tshua muaj cov ntsiab lus. Hauv qab ntawm Curie qhov kub thiab txias, thaum siv cov khoom sib nqus sab nraud, lub sijhawm sib nqus hauv txhua lub qhov muag sib nqus tau ua raws li cov kev taw qhia ntawm sab nraud magnetic teb, kom cov khoom muaj cov hlau nplaum loj dua.
