Taw qhia rau lub hauv paus ntsiab lus ntawm magnet attraction thiab hlau nqus

Vim li cas cov hlau nplaum nyiam hlau?
Tag nrho cov teeb meem yog tsim los ntawm cov molecules los yog atoms, thiab lub directional rotation ntawm electrons sab nraum lub nucleus yuav tsim magnetism. Feem ntau, qhov kev txiav txim molecular ntawm cov khoom tsis zoo, yog li cov hlau nplaum tsim los ntawm electron rotation tshem tawm ib leeg, yog li cov khoom zoo tib yam tsis muaj hlau nplaum, thaum hlau nplaum electrons sab nraum lub nucleus ntawm lub nucleus yog tag nrho rotating nyob rau hauv ib txoj kev, yog li cov hlau nplaum. muaj magnetism, thiab nws qhov loj yog sib npaug rau cov lej ntawm cov hlau nplaum tsim los ntawm cov electrons.

Cov txheej txheem ntawm cov hlau nplaum attracting hlau yog hu ua magnetization, uas yog hloov cov molecules disordered nyob rau hauv hlau mus rau hauv kev txiav txim los ntawm ib tug magnetic teb, ces hlau yuav zoo li hlau nplaum raws li ib tug hlau nplaum ua ntej.

Lub hauv paus ntsiab lus ntawm magnet attraction yog dab tsi?
Kev sib cuam tshuam quab yuam ntawm cov hlau nplaum yog ib qho zoo heev, yog li tib neeg kuj tseem mob siab rau lawv txoj kev tshawb fawb, yog li lawv tau siv dav hauv zej zog. Nws yuav siv sij hawm ntev heev los kawm txhua yam kev paub kom meej. Kariki Xiaobian yuav qhia rau koj txog lub hauv paus ntsiab lus ntawm kev sib nrig sib nyiam ntawm cov hlau nplaum. tus

Qhov kev nyiam ntawm A thiab B hlau nplaum yog tib yam li ntawm cov atoms, uas yog, qee cov atoms ntawm A hlau nplaum ua ke nrog qee cov atoms ntawm B hlau nplaum.

Kev nkag siab tseem ceeb: Cov hlau nplaum thiab cov hlau nplaum yuav tso cov cua sov (lub zog, cov khoom) hauv cov txheej txheem ntawm kev txav mus, uas yog, atoms sib xyaw ua ke kom tso tawm lub zog. Peb tsis hnov ​​nws hauv peb lub neej txhua hnub. Tsis txhob tso tseg lub zog tshuav raws li koj tus kheej xav.

Kev tsom xam: Lub hauv paus ntsiab lus ntawm cov hlau nplaum ywj pheej, cov khoom tawm los ntawm lub ntsej muag-spinning kheej kheej ntawm ib kawg ntawm cov hlau nplaum yuav raug cuam tshuam los ntawm cov khoom sab nraud txhua kauj ruam ntawm txoj kev. Tom qab cov txheej txheem txav tsis yooj yim, nws yuav taug kev tawm ntawm txoj kev nkhaus, thiab thaum kawg txav mus rau lwm qhov kawg thiab nkag mus rau qhov chaw tiv thaiv spinning. Ib qho kev nkag siab tseem ceeb heev: yog tias cov khoom txav mus, qhov ceev yog qhov tsis tu ncua, qhov loj dua qhov kev taw qhia ntawm cov khoom txav txav, qhov kev sib koom tes ntau dua tau txais los ntawm cov khoom sab nraud, yog tias cov khoom txav mus rau hauv txoj kab ncaj nraim, lub zog sib koom tes yog ntau dua. 0, uas yog, qhov txav ntawm qhov nkhaus Qhov ntau dua qhov curvature ntawm cov particle, lub zog ntau dua nws tau txais.

Kev txheeb xyuas dua: Thaum cov hlau nplaum A tau ntsib cov hlau nplaum B, cov khoom tawm los ntawm lub ntsej muag tig mus tom ntej ntawm ib kawg ntawm cov hlau nplaum B ncaj qha nkag mus rau hauv qhov chaw tiv thaiv ntawm cov hlau nplaum A, uas txhais tau hais tias cov khoom no tsis dhau mus ua haujlwm nyuaj, txo. qhov khoov ntawm ob qho kawg Txoj kev, uas yog, sab nraud quab yuam raug txo ntau heev. Vim li cas cov hlau nplaum nyiam ib leeg? Qhov laj thawj yog vim li cas cov hlau nplaum nyiam ib leeg yog vim lawv cov ferroelectricity (ib qho khoom muaj feem xyuam rau cov qauv ionic hauv cov hlau). Qhov no yog kev paub txog lub cev ntawm cov khoom siv. Nws yog qhov sib sib zog nqus. Aluminium, tooj liab, thiab lwm yam tsis muaj cov khoom no. Yog li tsis txhob attracted. Stainless hlau yog ib qho hlau alloy ntxiv nrog cov ntsiab lus xws li chromium. Vim hais tias impurities rhuav tshem cov thawj muaj pes tsawg leeg ntawm cov hlau cations, ua rau lawv poob lawv ferroelectricity, lawv tsis nyiam.
