There will be repulsion between $A$ and $B$ if $i$ is increased.

Vedclass · Answer

(A) According to Lenz's law,the direction of the induced current in a closed loop is such that it opposes the change in magnetic flux that produced it.When the current $i$ in coil $A$ is increased,the magnetic flux linked with coil $B$ increases.To oppose this increase in flux,coil $B$ will develop an induced current such that it creates a magnetic field in the opposite direction to the field produced by coil $A$.This results in the formation of like poles facing each other,leading to a repulsive force between the two coils.Therefore,if $i$ is increased,there will be repulsion between $A$ and $B$.

Two circular coils $A$ and $B$ are facing each other as shown in the figure. The current $i$ through coil $A$ can be altered.
