## The Attempt at a Solution

In this problem as the rod moves towards right, magnetic force of magnitude ilB starts acting towards left on the rod.This decreases the speed of the rod .The EMF induced in the rod is Blv where v is the instantaneous speed of the rod . As speed of the rod decreases , the induced EMF also decreases .

If rod were moving at constant speed , the current through the inductor would increase with time .But since EMF decreases with time , the current should decrease .

How should I take the two factors into account ?

Thanks
