In an inductor, the core provides the flux linkage path between the circuit winding and a non-magnetic gap, physically in series with the core. Virtually all of the energy is stored in the gap. High permeability fer-rites, or magnetic metal alloys such as Permalloy, are incapable of storing significant energy.
Inductor Cores – Material and Shape Choices
1. INTRODUCTION. An inductor is a current filtering device. By resisting change in current, the filter inductor essentially accumulates stored energy as an AC current crests each cycle, and releases that energy as it minimizes. Power inductors require the presence of an air gap within the core structure.

Energy Stored in an Inductor | Electrical Academia
Figure 2 Energy stored by a practical inductor. When the current in a practical inductor reaches its steady-state value of Im = E/R, the magnetic field ceases to expand. The voltage across the inductance has dropped to zero, so the power p = vi is also zero. Thus, the energy stored by the inductor increases only while the current is building up ...
