Question No : 10
               Two similar circular loops carry equal currents in the same direction. On moving coils further apart, the electric current will       

                a)          Increase in both          b)          Decrease in both     

                c)          Remain unaltered           d)          Increases in one and decreases in the second      

Answer No : 10
     (a)On moving the coils further apart initially the flux linked will reduced.Then, according to Lenz’s law current will increase in both the coils to increase the linked flux.
