Understanding Power Inductor Parameters
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.

Understanding Inductance: Energy Storage In Circuits
As the current in an inductor changes, so does its stored energy. When the current increases, the inductor absorbs energy from the circuit. When the current decreases, it releases energy back. The energy builds up while the current is rising to its steady-state value. Once the current stabilizes, the energy remains constant.
