A metallic square loop ABCD 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 AD, but not in BC
in BC, but not in AD
neither in AD nor in BC
in both AD and BC
Here VD−VA=VC−VB=Blv (motional e.m.f.)So, the electric field is induced in both AD and BC.
