Magnetic device energy storage and distribution. 3.1. Magnetic core and air gap energy storage. On the basis of reasonable energy storage, it is necessary to open an air gap on the magnetic core material to avoid inductance saturation, especially to avoid deep saturation. As shown in Fig. 1, an air gap Lg is opened on the magnetic core material.
Energy in an Inductor. When a electric current is flowing in an inductor, there is energy stored in the magnetic field. Considering a pure inductor L, the instantaneous power which must be supplied to initiate the current in the inductor is. Using the example of a solenoid, an expression for the energy density can be obtained.
An inductor, physically, is simply a coil of wire and is an energy storage device that stores that energy in the electric fields created by current that flows through those coiled wires.

An inductor is a component in an electrical circuit that stores energy in its magnetic field. Inductors convert electrical energy into magnetic energy by storing, then supplying energy to the circuit to regulate current flow. This means that if the current increases, the magnetic field increases. Figure 1 shows an inductor model.
An inductor is, therefore, characterized by its time constant (τ = tau), which is determined using the formula: τ = L R τ = L R. where. τ = time constant in seconds. L = inductance in henrys. R = resistance in ohms. This expression shows that a greater inductance and a lower resistance will cause a longer time constant.

Energy storage in an inductor. Lenz''s law says that, if you try to start current flowing in a wire, the current will set up a magnetic field that opposes the growth of current.

An ideal inductor has no resistance only inductance so R = 0 Ω and therefore no power is dissipated within the coil, so we can say that an ideal inductor has zero power loss. The Energy Stored When power flows into an inductor, energy is stored in its magnetic field.
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.
