how inductor introduces swing

can any one please explain from the very basics how and why an inductor increases a swing in a circuit?with some exaple numerical values

An inductor resists any change in current flow. To do this it will even produce current flow.

Simultaneously it produces EMF.

By 'increased swing' are you referring to the voltage swing across a coil when you apply sine waves? The induced EMF will even exceed the supply V as you watch an oscilloscope trace.

Seems paradoxical, doesn't it?

The easiest way to grasp how an inductor behaves is by animated simulation.

I have put videos on Youtube showing the basics of inductor operation. (One for DC, another for AC.)

My simulator graphically portrays changing supply voltage, current flow, EMF, and flux fields. From moment to moment at several frames per second.

I also put up demonstrations of a tank circuit in operation. And a sine sweep of a speaker crossover network.

Each video runs about 6 min.
