Beginner''s Corner: Inductors in DC Circuits
What is an Inductor. Like a capacitor, inductors store energy. But unlike capacitors that store energy as an electric field, inductors store their energy as a magnetic field. If we pass a current through an inductor we induce a magnetic field in the coil. The coil will store that energy until the current is turned off.

The potential energy that was stored in the coil is converted to kinetic energy and subsequently used to redistribute the charge until no current flows. At this point, the inductor has expended its stored energy. To restore energy, the external source must be turned back on, restoring the flow of charge and thereby restoring the magnetic field.

6 FAQs about [If the inductor stores energy]
How does a Magnetic Inductor store energy?
Instead, the energy is stored in the magnetic field as the rising current forces the magnetic lines of force to expand against their tendency to become as short as possible—somewhat as a rubber band stores energy when it is stretched. Figure 1 Determining the energy stored by an inductor
How does a pure inductor work?
This energy is actually stored in the magnetic field generated by the current flowing through the inductor. 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. Consider a simple solenoid.
What happens when power flows into an inductor?
When power flows into an inductor, energy is stored in its magnetic field. When the current flowing through the inductor is increasing and di/dt becomes greater than zero, the instantaneous power in the circuit must also be greater than zero, ( P > 0 ) ie, positive which means that energy is being stored in the inductor.
