However, in a purely inductive circuit, the current increases linearly with time, as the voltage remains constant for the circuit in Figure 1(a). This means there is a constant rate of change in the system''s current. Therefore, the average current value, I av, will be equal to I m / 2 as the current goes from zero to I m. And the resultant stored energy W will be equal to:

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.
