    With a changing current passing through it, the inductor wants to build up a magnetic field.

    That change in current is impeded by the very same magnetic field it's creating.

    If the field collapses in response to a decaying current, then the magnetic field tries to maintain the current flow.

    Energy is therefore stored in the magnetic field.

    Inductance is rather like inertia in that respect.
