Changing the amount of voltage applied to an inductor causes a corresponding change in current through the inductor. 

Due to the property of self-inductance, however, changes in inductor current always lag behind the changes in applied voltage.

When the applied voltage is a sinusoidal waveform, the voltage is changing constantly and the current is constantly lagging behind.


Unless stated otherwise, discussions of inductive reactance in AC circuits assume a sinusoidal voltage source.
