Energy Stored in an Inductor

In a pure inductor, the energy is stored without loss, and is returned to the rest of the circuit when the current through the inductor is ramped down, and its associated magnetic field collapses. Consider a simple solenoid. Equations ( 244 ), ( 246 ), and ( 249) can be combined to give. This represents the energy stored in the magnetic field ...

Why is flyback air gap needed for energy storage?

A flyback transformer doesn''t have the ampere-turn cancellation benefit of a forward converter, so the entire $ frac{1}{2}LI^2$ primary energy moves the core up its hysteresis curve. The air gap flattens the hysteresis curve and allows more energy handling by decreasing the permeability of the core.

limit the maximum energy storage in the core with no air gap. Since the magnetic core material itself is incapable of storing significant energy, energy storage is accomplished in a non-magnetic air gap(s) in series with the core. These gaps minimize the inductor variations caused by changes in core properties and help avoid core saturation.
