Taw qhia rau Electromagnets

Lub tshuab hluav taws xob yog ib qho khoom siv uas tsim hluav taws xob hluav taws xob thaum muaj hluav taws xob tam sim no ntws los ntawm nws. Ib tug conductive winding, matched rau lub hwj chim ntawm tam sim no, yog mob nyob ib ncig ntawm ib tug hlau core. Qhov tam sim no - nqa coil nthuav tawm cov hlau nplaum zoo li cov hlau nplaum, yog li lub npe electromagnet. Nws feem ntau yog ua nyob rau hauv ib lub bar lossis horseshoe zoo li ua rau cov tub ntxhais hlau yooj yim rau magnetize. Tsis tas li ntawd, txhawm rau xyuas kom cov electromagnet demagnetizes tam sim ntawd thaum lub hwj chim kaw, nws feem ntau yog ua los ntawm cov hlau mos los yog silicon steel, uas demagnetizes sai. Xws li electromagnet yog sib nqus thaum lub zog, thiab cov hlau nplaum ploj thaum lub hwj chim raug tua. Electromagnets muaj ntau daim ntawv thov nyob rau hauv peb lub neej niaj hnub, thiab lawv cov invention tau zoo heev ua rau lub hwj chim ntawm generators.
