As the electric current produces a concentrated magnetic field around the coil, this field flux equates to a storage of energy representing the kinetic motion of the electrons through the coil. The more current in the coil, the stronger the magnetic field will be, and the more energy the inductor will store.

Inductor

An inductor, also called a coil, choke, or reactor, is a passive two-terminal electrical component that stores energy in a magnetic field when electric current flows through it. [1] An inductor typically consists of an insulated wire wound into a coil.. When the current flowing through the coil changes, the time-varying magnetic field induces an electromotive force (emf) in the conductor

Energy stored in an inductor

Energy stored in an inductor is the electrical energy accumulated in the magnetic field created by the flow of current through the inductor. When current passes through the inductor, it generates a magnetic field around it, and this energy can be retrieved when the current changes.

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.
