Question

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

  1. In AD, but not in BC    
  2. In BC, but not in AD    
  3. Neither in AD nor in BC    
  4. In both AD and BC    

The correct answer is: In both AD and BC


    Both AD and BC are straight conductors moving in a uniform magnetic field and emf will be induced in both. This will cause electric fields in both, but no net current flows in the circuit
