Inductor saturation energy storage
Controlling and Preventing Core Saturation in Inductors
In saturation, however, the magnetic flux is almost constant. As a result, no voltage is induced across an inductor when its core saturates. Instead, the inductor behaves almost like a short circuit. Saturation Limits the Maximum Magnetic Field Force. To avoid saturation, we need to limit the magnetic flux density (B) to below B sat.
Modeling Inductors with LTspice

inductance
We have a core of some nominal energy storage capacity, independent of the winding we put around it; the question, then, is what impedance -- what ratio of voltage to current -- the circuit needs. The turns count is the transformer matching ratio for an inductor to the circuit. And when the inductor saturates, that ratio changes.
