#### How does an inductor store energy?

Energy Storage Process. As the current flows through the inductor, the magnetic field builds up and stores energy. The energy stored in the inductor is proportional to the square of the current and the inductor''s inductance. When the current decreases or stops, the magnetic field collapses, and the stored energy is released back …
