Time Constant in DC Circuit Inductors
An inductor is, therefore, characterized by its time constant (τ = tau), which is determined using the formula: τ = L R τ = L R. where. τ = time constant in seconds. L = inductance in henrys. R = resistance in ohms. This expression shows that a greater inductance and a lower resistance will cause a longer time constant.

Somewhere in that paper, they choose differently than I did above, saying that the inductor''s energy represents potential, and not kinetic, energy. But like I said, you get to choose. So I prefer to think of the Coulombs on a capacitor as position coordinates and the Webers of an inductor as momentum coordinates, which swaps those roles.

To model the "heat" of the inductor, you need to define the winding resistance of the inductor. In your model circuit, there does not appear to be any winding resistance (meaning that is negligible compared to the resistors R), so there - in this case - is no difference in the heat generated by the inductor.
