Inductors
Inductors are two terminal, passive energy storage devices. They store electrical potential en-ergy in the form of an magnetic field around the current carrying conductor forming the inductor. Actually, any conductor has the properties of an inductor. Most inductors are formed by fashion-ing the conductor into a cylindrical coil.

Inductors: Energy Storage Applications and Safety Hazards
The inductor subdues any output current fluctuations by changing its behavior between a load and a supply based on the SMPS current ripple. The inductor behaves like a load and stores energy to prevent ripples from producing excess current. It acts like a current supply when the ripple reduces the current value.
