Inductor
In addition, inductors are employed in transformers for power grids, and as energy storage devices in some switched-mode power supplies. Overview When an electric current first begins to pass through an inductor (coil of wire), the inductor resists the flow of current, as a magnetic field is building up around the inductor. [1]

Flyback vs. Coupled inductors vs. Transformer?
Energy storage is important for a fly-back transformer because energy is stored in the core and air-gap (in fact largely in the air-gap) for part of a cycle, and then released later in the cycle. In general, we can express a nonideal transformer as a "wye" of inductors (and an ideal 1:1 transformer, if we still need to express isolation

They also approximate the bulk properties of capacitance and inductance that are present in any physical system.
Why is flyback air gap needed for energy storage?
The term "Flyback Transformer" is a little misleading and its more useful to consider it as coupled inductors rather than a transformer because the action is quite different with a conventional transformer energy is going into the primary and out of the secondary at the same time it does not store energy.
