Why do we want gap in the core material while designing inductor?
In fact, energy storage in a transformer is a Bad Thing, needing snubbers to protect inverter drives. This needs a low reluctance path, so no air gap, as as high a permeability as possible. ... If we make an air-core inductor, this is invariably the thing that limits the maximum energy storage. If we wanted to run a higher current, we could do ...

Toroidal inductors. The prior discussion assumed μ filled all space. If μ is restricted to the interior of a solenoid, L is diminished significantly, but coils wound on a high-μ toroid, a donut-shaped structure as illustrated in Figure 3.2.3(b), yield the full benefit of high values for μ.Typical values of μ are ~5000 to 180,000 for iron, and up to ~10 6 for …

turns ratio. Energy storage in a transformer core is an undesired parasitic element. With a high permeability core material, energy storage is minimal. 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.
