Dab tsi yog cov yam ntxwv ntawm Electromagnet?

Sib Nqus Field Strength
Ib qho ntawm cov yam ntxwv tseem ceeb ntawm electromagnet yog nws lub zog magnetic teb. Lub zog hlau nplaum yog cuam tshuam los ntawm qhov loj thiab kev taw qhia ntawm qhov tam sim no ntws los ntawm electromagnet lub kauj. Thaum tam sim no ntws los ntawm lub kauj, muaj zog hlau nplaum yog tsim nyob ib ncig ntawm nws. Lub zog ntawm lub magnetic teb yog ncaj qha proportional rau qhov loj ntawm qhov tam sim no, thiab kuj muaj feem xyuam rau cov yam xws li cov xov tooj ntawm cov kauj voj voog thiab cov khoom ntawm cov tub ntxhais hlau.

Number of Coil Turns
Tus naj npawb ntawm cov coil tig kuj yog ib qho tseem ceeb ntawm cov electromagnet. Qhov ntau lem, qhov muaj zog ntawm magnetic teb, thiab lub zog ntawm electromagnet qhov attraction. Yog li ntawd, thaum tsim ib lub tshuab electromagnet, tus naj npawb ntawm cov kauj yuav tsum tau xaiv raws li cov kev xav tau tshwj xeeb kom tau raws li qhov xav tau kev nyiam.

Kev siv tam sim no
Kev siv tam sim no yog lwm qhov tseem ceeb cuam tshuam rau cov yam ntxwv ntawm electromagnet. Feem ntau, qhov attraction ntawm electromagnet nce nrog nce tam sim no. Txawm li cas los xij, yog tias qhov tam sim no siab dhau lawm, nws tuaj yeem ua rau cov hlau nplaum hluav taws xob overheat lossis hlawv tawm. Yog li ntawd, thaum siv lub tshuab hluav taws xob, qhov tsim nyog siv tam sim no yuav tsum raug xaiv raws li qhov xwm txheej tshwj xeeb.

Electromagnetic Force
Electromagnetic quab yuam yog ib qho tseem ceeb tshaj plaws yam ntxwv ntawm ib tug electromagnet, xa mus rau lub magnetic quab yuam generated los ntawm tam sim no nyob rau hauv lub kauj. Thaum lub tshuab hluav taws xob muaj zog, nws tsim cov hlau nplaum uas nyiam cov tub ntxhais hlau thiab lwm yam khoom hlau; qhov no yog li ntawd -hu ua electromagnetic force. Lub zog ntawm electromagnetic quab yuam nyob ntawm cov yam ntxwv xws li kev siv tam sim no, tus lej ntawm cov coil tig, thiab cov khoom siv tseem ceeb. Thaum tsim ib lub tshuab electromagnetic, nws yog ib qho tsim nyog yuav tau xaiv lub zog hluav taws xob tsim nyog raws li qhov yuav tsum tau ua.
