A magnetic flux of 5 microweber is linked with a coil when a current of 1 MA flows through it.What is the self inductance of the coil ?

Will an induced current be always produced whenever there is change of magnetic flux linked with a coil?

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 . Inductors of inductance L_1 and L_2 are connected in series. The effective inductance is:
