DC electromagnets yog cov khoom siv tseem ceeb hauv lub neej niaj hnub, pab tsim khoom thiab lub neej txhua hnub. Lawv daim ntawv thov yog dav hauv lub neej txhua hnub.
Electromagnetic Cranes: Qhov no yog ib daim ntawv thov ntawm electromagnets hauv lub neej txhua hnub. Thaum energized, lub electromagnet tsim ib tug muaj zog attraction quab yuam, muaj peev xwm ntawm attracting hlau ntaub ntawv ib zaug. Los ntawm kev txav tus neeg hlau caj npab thiab tom qab ntawd de- zog, cov khoom hlau loj tuaj yeem txav tau. Qhov no ua rau txav cov khoom loj, hnyav hlau yooj yim dua.
Electromagnetic Relays: Electromagnets pab tswj chaw taws teeb ntawm lub zog tam sim no.
Hluav taws xob Tswb: Thaum lub tshuab hluav taws xob muaj zog, lub phaj hlau hauv lub tswb raug nyiam thiab sib tsoo nrog lwm lub phaj hlau, ua suab nrov. Thaum lub electromagnet yog de-energized thiab cov hlau daim hlau rov qab mus rau lawv cov thawj txoj hauj lwm, energizing dua ua rau lawv sib tsoo thiab tsim suab. Lub voj voog no rov ua dua, ua lub suab nrov nrov.
Maglev Tsheb ciav hlau: Maglev tsheb ciav hlau siv electromagnets kom ua tiav levitation, tso cai rau lawv kom tsis txhob sib cuag nrog av thiab txo kev sib txhuam. Cov hom tsheb no muaj qhov zoo xws li kev kub ceev, tsis muaj kuab paug, thiab tsis muaj suab nrov.
