Self inductance or coefficient of self induction Whenever an electric flowing through a coil changes, the magnetic flux linked with the circuit also changes. And an induced emf is produced in the circuit. This phenomenon is called self-induction. The magnetic flux linked with the coil (phi) is proportional to the current (I) flowing in te circuit i.e. phi propto I . If inductors of inductances L_1 and L_2 are connected in parallel, the effective inductance is:
