Magnets tsis tsuas yog nyiam hlau,hlau nplaumtuaj yeem ua rau cov hlau nplaum sib nqus thiab muaj cov yam ntxwv ntawm kev nyiam cov khoom siv ferromagnetic xws li hlau, npib tsib xee, cobalt, thiab lwm yam hlau. Cov hlau nplaum feem ntau nyiam cov hlau vim tias, nyob rau hauv qhov kev xav tau ntawm sab nraud magnetic teb, micro-magnetic teb ntawm cov hlau nws tus kheej yuav hloov raws li cov kev taw qhia ntawm cov hlau nplaum kab, uas ua rau lub magnetic teb raws li cov kev taw qhia ntawm sab nraud. magnetic teb kab ntawm cov hlau nplaum. Tag nrho cov txheej txheem ntawm cov khoom siv hlau yog nqus nyob rau hauv tag nrho cov txheej txheem ntawm kev quab yuam hloov cov kev taw qhia kev sib hloov ntawm cov khoom siv hluav taws xob sab hauv. Cov khoom xyaw nquag ntawm cov hlau nplaum yog hlau, cobalt, npib tsib xee, thiab lwm yam atoms. Cov qauv sab hauv ntawm lawv cov atoms txawv heev, thiab lawv muaj lub sijhawm sib nqus lawv tus kheej. Yog li dab tsi hlau tsis nyiam los ntawm cov hlau nplaum?
1. Cov hlau uas tuaj yeem nyiam los ntawm cov hlau nplaum yeej muaj tsawg heev, tsuas yog txwv rau ob peb hom hlau nplaum xws li hlau, npib tsib xee, cobalt, thiab lwm yam, thiab feem ntau lwm yam hlau xws li kub, nyiaj, tooj liab, txhuas, tin. , txhuas, titanium, thiab lwm yam yog tsis yooj yim los ntawm cov hlau nplaum.
2. Cov hlau nplaum yog ib yam khoom uas tuaj yeem tsim cov hlau nplaum. Nws yog magnetic dipole, uas tuaj yeem nyiam cov ntaub ntawv ferromagnetic thiab tshuaj xws li hlau, npib tsib xee, cobalt, thiab lwm yam hlau. Kev txheeb xyuas ntawm cov hlau nplaum yog ua raws li cov filament uas tau muab tshem tawm hauv cov hlau nplaum, cov hlau nplaum nyob rau sab qaum teb yog hu ua tus ncej qaum teb lossis N ncej, thiab cov hlau nplaum nyob rau sab qab teb yog tus taw qhia ncej lossis S ncej. Cov hlau nplaum nrog cov ncej sib txawv nyiam ib leeg, thiab cov hlau nplaum nrog tib tus ncej sib tsoo. Lub compass ncej thiab sab qaum teb ncej attracts opposites, ncej thiab ncej repel ib leeg, thiab tus ncej thiab ncej ntxeev ib leeg.
