Nyob rau sab nraud magnetic teb, cov ntaub ntawv tuaj yeem qhia peb qhov xwm txheej: ① cov uas tsis nyiam los ntawm cov hlau nplaum yog hu ua cov khoom siv diamagnetic; ② Cov uas tsis muaj zog txaus nyiam los ntawm qhov chaw sib nqus yog hu ua cov ntaub ntawv paramagnetic; ③ Cov khoom siv ferromagnetic yog nyiam los ntawm cov hlau nplaum. Nws magnetism nce sharply nrog lub zog ntawm sab nraud magnetic teb, thiab tseem tuaj yeem khaws nws cov hlau nplaum tom qab tshem tawm cov hlau nplaum sab nraud. Hauv cov khoom siv hlau, feem ntau cov hlau hloov pauv muaj paramagnetism; Tsuas yog ob peb cov hlau xws li Fe, Co thiab Ni yog ferromagnetic.
Cov ntsiab lus tseem ceeb ntawm cov khoom siv hlau nplaum ruaj khov hauv cov hlau yog Fe, Co, Ni thiab qee lub ntiaj teb tsis tshua muaj. Puas muaj tsawg lub ntiaj teb nyob rau hauv cov hlau nplaum ruaj khov siv? Cobalt series, hlau? Chromium? Cobalt series thiab manganese? aluminium Carbon alloy.
Cov hlau nplaum sib nqus tau siv dav hauv lub zog, hluav taws xob, khoos phis tawj, tswj tsis siv neeg thiab electro optics.
