Cov xim nplhaib inductor yog cov khoom siv rov ua haujlwm. Inductors feem ntau yog siv hauv hluav taws xob circuits. Ib tug hlau yog muab tso rau ntawm ib tug hlau core los yog ib tug cua-core coil yog ib tug inductor. Thaum cov tam sim no dhau los ntawm ib feem ntawm cov xaim, qee qhov hluav taws xob electromagnetic yuav raug tsim nyob ib ncig ntawm cov hlau, thiab qhov hluav taws xob hluav taws xob no yuav muaj kev cuam tshuam rau cov hlau hauv qhov chaw electromagnetic. Peb hu cov nyhuv electromagnetic induction. Yuav kom ntxiv dag zog rau electromagnetic induction, tib neeg feem ntau cua ib qho hluav taws xob rwb thaiv tsev rau hauv ib lub coil nrog qee qhov kev hloov pauv, thiab peb hu rau lub kauj vab inductance. Rau kev txheeb xyuas yooj yim, cov kauj inductance feem ntau hu ua inductor lossis inductor.
