Electromagnets muaj feem ntau ntawm cov kev siv hauv lub neej txhua hnub. Lub tshuab electromagnet yog ib daim ntawv thov ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv (electromagnetic magnetic), thiab muaj kev sib raug zoo nrog rau lub neej, xws li electromagnetic relays, electromagnetic cranes, hlau nplaum sib nqus thiab ua li ntawd. Electromagnets muab faib ua ob hom: DC electromagnets thiab AC electromagnets. Yog tias cov electromagnets raug faib raws li lub hom phiaj, lawv tuaj yeem faib rau hauv tsib yam nram qab no: (1) Traction electromagnets-tsuas yog siv los rhuav cov khoom siv thiab qhib lossis kaw ntau yam khoom siv kom ua haujlwm tsis tiav. (2) Kev siv lub tshuab electromagnet - siv raws li kev nqa khoom nqa ferromagnetic cov ntaub ntawv xws li hlau kiv, hlau, thiab hlau. (3) Nres electromagnet - feem ntau siv rau kev tsav tsheb kom ua tiav qhov chaw nres tsheb. (4) Electromagnetic systems tsis siv khoom siv - xws li electromagnetic relays rau electromagnetic relays thiab contactors, electromagnetic tawm rau kev hloov tsis siv neeg, thiab kev khiav hauj lwm electromagnets. (5) Electromagnets rau lwm tus siv - xws li cov tshuab grinders 'electromagnetic chucks thiab electromagnetic vibrators.
