Cov muaj pes tsawg leeg ntawmhlau nplaumyog hlau, cobalt, npib tsib xee, thiab lwm yam atoms nrog ib tug tshwj xeeb sab hauv, thiab cov atoms lawv tus kheej muaj magnetic moments. Feem ntau, kev npaj ntawm cov pob zeb hauv av molecules yog chaotic. Lawv thaj chaw sib nqus cuam tshuam rau ib leeg thiab tsis qhia cov hlau nplaum, tab sis nyob rau hauv kev taw qhia ntawm sab nraud quab yuam (xws li magnetic teb), kev taw qhia ntawm lawv cov molecules yuav zoo li qub, thiab lawv cov hlau nplaum yuav tshwm sim, uas yog qhov peb feem ntau. hu cov hlau nplaum.
Yam dab tsi yuav cuam tshuam rau tus nqi ua cov hlau nplaum?
1. Kev ua haujlwm ntawm cov hlau nplaum, qhov kev ua tau zoo ntawm cov hlau nplaum ntau dua, tus nqi siab dua thiab tus nqi siab dua, thiab cov hlau nplaum yuav nkig ntau dua, yog li qhov poob yuav loj heev hauv cov txheej txheem ntawm kev ua.
2. Batch loj, raws li peb txhua tus paub, batch loj muaj kev cuam tshuam zoo rau tus nqi. Qhov loj dua qhov kom muaj nuj nqis, tus nqi qis dua. Qhov laj thawj tseem ceeb ntawm kev txo tus nqi yog tias cov neeg ua haujlwm, kev thauj mus los, thiab kev ua haujlwm yog txhua yam kev sib koom ua ke.
3. Qhov loj ntawm cov hlau nplaum. Qhov loj ntawm qhov loj ntawm cov hlau nplaum, tus nqi ntau dua. Hais txog kev hais lus, tus nqi ua haujlwm ntawm cov hlau nplaum yuav siab dua.
4. Magnet kam rau ua raws li qhov yuav tsum tau ua, qhov nruj dua qhov yuav tsum tau ua siab ntev, tus nqi ua haujlwm ntau dua, thiab cov khoom seem ntau dua, yog li tus nqi siab dua.
5. Cov duab ntawm cov hlau nplaum, qhov nyuaj ntawm cov hlau nplaum, cov txheej txheem ua haujlwm ntau dua, thiab cov nqi ua haujlwm yuav nce ntxiv, thiab cov txheej txheem ua ntau dua, cov khoom seem yuav nce ntxiv.
6. Tus nqi seem yog siab lossis qis. Nws yog qhov pom tseeb tias qhov siab dua cov khoom seem, cov khoom siv raw xav tau ntau dua, thiab tus nqi yuav nce ntxiv.
