Ib electromagnet yog a hom hlau nplaum qhov twg sib nqus teb yog tsim los ntawm hluav taws xob tam sim no. Hluav taws xob feem ntau muaj cov hlau qhov txhab rau hauv ib lub kauj.

Cov lus nug tseem yog, qhov txawv ntawm cov hlau nplaum thiab electromagnet yog dab tsi?

Ib electromagnet yog tsim los ntawm cov hlua hlau uas ua haujlwm zoo li hlau nplaum thaum muaj hluav taws xob los ntawm nws. Feem ntau ib electromagnet yog qhwv ib ncig ntawm ib qho tseem ceeb ntawm cov khoom siv ferromagnetic zoo li hlau, uas ua kom zoo dua qub sib nqus teb ua los ntawm lub kauj.

Ib yam nkaus, qhov sib txawv ntawm cov hlau nplaum ruaj khov thiab cov tshuab hluav taws xob muab ib qho piv txwv ntawm txhua tus? hlau nplaum tas mus li yog ua los ntawm "nyuaj" sib nqus cov khoom uas tuav nws hlau nplaum dhau lub sij hawm ntev. Cov magnetism hauv lub tshuab hluav taws xob yog tsim los ntawm tam sim no khiav los ntawm ib tug coil ntawm insulated hlau uas yog mob nyob ib ncig ntawm ib daim ntawm "mos" sib nqus khoom

Tsuas yog li ntawd, puas yog tag nrho cov hlau nplaum electromagnet?

Muaj ob hom hlau nplaum : mus tas li hlau nplaum (ntawm sab xis), thiab electromagnets . Cov lus nug tiag tiag yog nug yog qhov ruaj khov hlau nplaum ntawm sab xis, tshwm sim vim tias muaj coob leej me me electromagnets ntawm qib atomic ntxiv mus rau thaj chaw ruaj khov. Thawj qib lus teb yog yog.

Dab tsi yog qhov muaj zog electromagnet lossis hlau nplaum ruaj khov?

Hluav taws xob yeej yog muaj zog tshaj hlau nplaum ruaj khov . Cov hlau nplaum ruaj khov muaj zog sib nqus teb vim tau pom ib txwm tab sis sib nqus ntawm electromagnets tuaj yeem hloov kho los ntawm kev hloov pauv qhov loj ntawm qhov tam sim no dhau los ntawm cov coil qhwv ib ncig ntawm nws lossis hloov qhov tsis muaj qhov hloov ntawm lub kauj.
