Magnetic marudzi eSuper Akasimba Magnets: Mukushaikwa kwekunze kwemagineti, nekuda kwekutsinhana kwema electrons kana kumwe kudyidzana pakati peatomu dziri padyo negineti, nguva dzadzo dzemagineti dzinokunda pesvedzero yekufamba kwekupisa, magineti akasimba ari muhurongwa hwakadzimwa zvishoma, zvichikonzera chiitiko. yenguva yemagineti.Kana magineti ekunze akaiswa, magineti ayo anoshanduka neaya ekunze magineti akafanana neaya eferromagnetic zvinhu.Ferromagnetism uye antiferromagnetism zvine chimiro chemuviri chakafanana, asi antiparallel spin magineti nguva mumaferromagnets akasiyana magnitude, saka pane chikamu chinodzikisira chinozviitira magineti nguva, yakafanana neferromagnet.Ferrites kazhinji ferromagnets.
Diamagnetism inguva apo magineti nguva dzemaerekitironi ari mumaatomu echinhu ichidzima imwe neimwe kunze uye nguva yemagineti yakasanganiswa i zero.Asi apoSimba Rare Earth Magnetsinoiswa pasi pekunze remagineti, iyo erekitironi orbital motion inoshanduka, uye inoburitsa diki diki rekubatana remagineti iri mhiri kwakatarisana nekunze kwemagineti.Magineti akasimba nokudaro anomiririra magineti echinhu uye kusanzwa kunova nhamba diki isina kunaka.Magnetic susceptibility ireshiyo yenguva yemagineti yechinhu chiri pasi pekunze kwemagineti (inozivikanwa semagineti) kusimba remagineti, nechiratidzo κ.Kubatwa kwe general antimagnetic zvinhu kungangoita minus chikamu chimwe pamiriyoni (-10-6).
Iyo magnetic susceptibility yeparamagnetism yakanaka, 1 ~ 3 magnitude yakakura kudarika diamagnetism, X inenge 10-5 ~ 10-3, inoteerera mutemo waCurie kana mutemo waCurie-Weiss.Kana pane ayoni, maatomu kana mamorekuru asina maerekitironi maviri ari mu aYakasimba Yechigarire Magnet, kune spin angular kasi uye orbital angular kumhanya kwemaerekitironi, saka pane spin magineti nguva uye orbital magineti nguva.Pasi peiyo yekunze magineti, iyo yekutanga kusagadzikana magineti nguva ichave yakatarisana, nekudaro ichiratidza paramagnetism.
