Inductors

The inductor is another example of a passive element that stores energy. Inductors do this by storing energy in the form of a magnetic field, or B-field.

An inductor consists of a coil of wire wound around an iron or non-magnetic (air) core. Current passing through the inductor establishes a magnetic flux. The resulting magnetic field can store energy that is transferred back and forth between the electric circuit and the magnetic circuit produced by the inductor. The amount of inductance is measured in Henrys, the amount of magnetic flux produced by each ampere of current.

    V = L*ΔI/ΔT        (electrical definition for inductance)
