Inductance is fundamentally influenced by the physical and geometrical characteristics of the inductor, namely the number of turns of wire, the cross-sectional area of the core, and the distance between the windings.

The current passing through the wire does not determine the amount of inductance itself. Instead, it affects the behavior of the inductor in terms of the magnetic field generated and resulting voltage (according to Lenz's Law). While an increase in current can impact the energy stored in the inductor and the inductive reactance in a circuit, the inductance value derived from a particular inductor design remains constant for a given physical configuration.

Thus, the factors that directly contribute to the value of inductance are intrinsic to the inductor's physical attributes, rather than the operational parameters such as current.
