1. Antimagnetic
Thaum lub magnetization M tsis zoo, cov khoom zoo li diamagnetic. Cov pa co xws li Bi, Cu, Ag, thiab Au muaj cov khoom zoo li no. Hauv ib lub teb chaw magnetic, qhov nqus hlau induction hauv xws li ib qho chaw nruab nrab yog tsawg dua qhov kev sib nqus induction M hauv vacuum. Lub nqus hlau ntawm lub atoms (ions) ntawm cov khoom siv hlau diamagnetic yuav tsum yog xoom, piv txwv li yog tsis muaj qhov tob hlau ntev lawm. Thaum cov khoom siv diamagnetic yog muab tso rau hauv ib qho chaw sib nqus sab nraud, lub sab nraud magnetic hloov pauv ntawm orrons ntawm electrons, induces ib lub caij sib dhos tig mus rau qhov ntawm sab nraud magnetic teb, thiab qhia nws tus kheej ua qhov pom kev. Yog li, diamagnetic kuj pib los ntawm kev hloov ntawm cov xeev orbital ntawm electrons hauv atoms. Lub diamagnetic tsis kam ntawm cov khoom siv diamagnetic feem ntau muaj zog heev, thiab qhov sib zog nqus tshuaj H yog feem ntau li ntawm -10 ^ -5, nws yog ib qho txiaj ntsig zoo.
2. Paramagnetism
Tus cwj pwm tseem ceeb ntawm cov khoom siv paragent yog tias muaj ib qho chaw ruaj khov ntawm lub cev tsis hais nyob hauv lub koos poom, txawm tias tsis yog ib qho chaw ua magnetic. Txawm li cas los xij, thaum tsis muaj ib lub teb chaw magnetic, vim lub cua sov thermal kev vibration ntawm lub atoms ntawm cov khoom paragnetic, tsis muaj, tsis muaj magnetism; nyob rau hauv qhov kev txiav txim ntawm ib sab nraud magnetic teb, txhua atom lub sib nqus lub caij no yog tus nquag taw qhia, thiab cov ntaub ntawv khoom muaj zog heev cov khoom sib nqus. Lub magnetization yog raws nraim nrog cov kev taw qhia ntawm tus sab nraud magnetic teb.
Nws zoo thiab nruj nreem rau sab nraud magnetic teb H.
Ntxiv rau H, cov khoom sib nqus ntawm cov khoom siv cov khoom siv paramagnetic nyob ntawm qhov kub thiab txias. Nws raug mob H yog inversely proportional mus rau qhov kub siab T.
Hauv cov mis, C yog hu ua Curie tsis tu ncua thiab nyob ntawm qhov magnetization thiab lub sib nqus lub caij ntawm cov khoom siv paragent.
Qhov sib nqus ntawm cov khoom magnetic ntawm cov ntaub ntawv tseem ceeb me me, thiab H yog txog 10 ^ -5 ntawm qhov chaw sov. Feem ntau cov atoms lossis molecules uas muaj ib qho khib nyiab ntawm electron, electrons tsis sau lub plhaub atoms lossis ions, xws li kev hloov cov khoom, cov khoom tsis tshua muaj zog, steel ntsiab, thiab txhuas thiab platinum co, yog cov khoom paug.
