Cov khoom tseem ceeb ntawm DC electromagnet yog nws cov khoom tseem ceeb, feem ntau yog siv los ua thiab mloog cov kab hlau nplaum sib nqus, txhim kho cov khoom siv hluav taws xob.
Kev xaiv ntawm cov khoom tseem ceeb ncaj qha cuam tshuam rau electromagnet qhov kev ua tau zoo, lub neej ntev, thiab kev siv lub zog. DC electromagnet core cov ntaub ntawv muaj xws li cov hlau mos, silicon steel, hlau ntshiab, thiab ferrite.
Cov hlau mos: siab permeability thiab qis coercivity, yooj yim rau magnetize thiab demagnetize, haum rau daim ntaub ntawv yuav tsum tau nquag hloov.
Silicon steel: Ntxiv silicon tsub kom qhov kev tiv thaiv thiab txo qhov poob tam sim no, haum rau siab - zaus lossis AC electromagnets.
Cov hlau ntshiab: Cov permeability siab, tab sis tus nqi siab dua, feem ntau yog siv nyob rau hauv siab -kev ua tau zoo electromagnets.
Ferrite: Kev tiv thaiv siab, zoo siab - tus yam ntxwv zaus, tab sis qis permeability, haum rau siab - zaus, qis - fais fab electromagnets.
