The electric field/e.m.f. is induced in sides AD and BC, both in the same direction. However, there will be no current in loop as the potential of A is same as that of B and potential of D is same as that of C

Q. A metallic square loop $A BC D$ is moving in its own plane with velocity $v$ in a uniform magnetic field perpendicular to its plane as shown in Fig. An electric field is induced.

In $A D,$ but not in $BC$

In $BC$ , but not in $A D$

Neither in $A D$ nor in $BC$

In both $A D$ and $BC$
