Inductance is therefore also proportional to the energy stored in the magnetic field for a given current. This energy is stored as long as the current remains constant. If the current decreases, the magnetic field decreases, inducing a voltage in the conductor in the opposite direction, negative at the end through which current enters and positive at the end …

Inductance is the ability of a structure to store energy in a magnetic field. The inductance of a structure depends on the geometry of its current-bearing structures and the permeability of the intervening medium. Note that inductance does not depend on current, which we view as either a stimulus or response from this point of view.
