Explanation:
When the rate of change of current is unity
then the induced emf = coefficient of self-induction.
i.e. the coefficient of self induction of a coil is equal to the flux linked with the coil when the current in it is 1 amp. Hence coefficient of self induction is equal to the emf induced in the coil when the rate of change of current in the coil is unity.
