Question

(i) Define mutual inductance.
(ii) A pair of adjacent coils has a mutual inductance of $$1.5\ H$$. If the current in one coil changes from $$0$$ to $$20\ A$$ in $$0.5\ s$$, what is the change of flux linkage with the other coil?


Solution

(i) : Mutual inductance $$(M)$$ is the property of the coils that a current is induced in the secondary coil if there is a change in current in the primary coil.
Its SI unit is Henry.
(ii) :
Given :  $$M = 1.5 H$$    
Change of current  $${\Delta I}= {20-0} = 20 \ A$$
Change of flux  $$\Delta \phi =  M \Delta I = 1.5\times 20  =30 \ Wb$$
