Inductance of a Coil

The inductance of a coil refers to the electrical property the inductive coil has to oppose any change in the current flowing through it. It therfore follows that inductance is only present in an electric circuit when the current is changing. Inductors generate a self-induced emf within themselves as a result of their changing magnetic field.
