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 the figure. An electric field is induced.

Options

A. in AD, but not in BC
B. in BC, but not in AD
C. neither in AD nor in BC
D. in both AD and BC

Answer

A conducting square loop of side L and resistance R moves in its plane with a unifrom velocity v perpendicular to one of its sides. A magnetic induction B constant in time and space, pointing perpendicular and into the plane of the loop exists every where. the current induced in the loop is
