Inductors
Inductors oppose changes in the magnitude or directionality of electric current. Inductors store energy in a magnetic field. This magnetic field produces a voltage in response to a change in current. The voltage produced by an inductor opposes the change in current. Thus, an inductor works to oppose any changes in current.
