Magnetism yog ib feem ntawm kev sib xyaw electromagnetic quab yuam. Nws yog hais txog lub cev phenomena tshwm sim los ntawm lub zog los ntawm hlau nplaum , cov khoom uas tsim cov teb uas nyiam los yog tawm tsam lwm yam khoom. Mus tas li hlau nplaum , ua los ntawm cov ntaub ntawv xws li hlau, muaj kev cuam tshuam zoo tshaj plaws, hu ua ferromagnetism.

Ib yam li ntawd, magnetism yog dab tsi hauv cov ntsiab lus yooj yim?

Hauv physics, hlau nplaum yog ib lub zog uas tuaj yeem nyiam (rub los ze zog) lossis rub tawm (them tawm) cov khoom uas muaj cov khoom sib nqus xws li hlau hauv lawv (cov khoom sib nqus). Hauv lus yooj yim dua , nws yog ib yam khoom ntawm tej yam khoom uas rub los ze zog los yog tawm tsam lwm yam khoom.

Kuj Paub, dab tsi yog lub ntsiab lus ntawm magnetism hauv science? Magnetism yog lub zog nyiam. Nws yog hais txog qhov attraction rau hlau thiab lwm yam hlau nyob rau hauv hluav taws xob tam sim no thiab hlau nplaum , los yog mus rau lwm yam kev nyiam - qhov twg tib neeg xav nyob ze rau ib leeg. Chemistry thiab ntiaj teb kev kawm yog ob chav kawm koj yuav kawm txog hlau nplaum hauv.

Ntxiv mus, dab tsi yog qhov ua rau hlau nplaum?

Magnetism yog ua rau los ntawm kev txav ntawm cov nqi hluav taws xob. Txhua yam khoom yog tsim los ntawm cov khoom me me hu ua atoms. Yog vim li cas cov ntaub ntawv xws li ntaub los yog ntawv thiaj li hais tias tsis muaj zog hlau nplaum. Nyob rau hauv cov khoom xws li hlau, cobalt, thiab npib tsib xee, feem ntau ntawm cov electrons spin nyob rau hauv tib txoj kev.

Kuv tuaj yeem hais li cas txog hlau nplaum?

North ncej ntawm ib hlau nplaum attracts tus ncej qab teb ntawm ib tug thib ob hlau nplaum , thaum tus ncej qaum teb ntawm ib hlau nplaum repels lwm tus hlau nplaum qaum teb. Yog li peb muaj qhov sib xws hais : zoo li ncej repel, tsis zoo li ncej nyiam. A hlau nplaum tsim ib cheeb tsam tsis pom ntawm hlau nplaum nyob ib ncig ntawm nws hu ua magnetic teb.
