    A conducting square loop of side L and resistance R moves in its plane with a uniform velocity V perpendicular to one of its sides. A magnetic field, B, constant in space and time. Pointing perpendicular and into the plane of the loop exists everywhere as shown in figure. The current induced in the loop is:            

    A)  BLV/R clockwise     

    B)  BL V/R anti clockwise

    C)  2BLV/R anti-clockwise

    D)  zero                  

    Correct Answer: D

    Solution :

    Since the magnetic field is constant with time and space and exists everywhere, there is no change in magnetic flux when the loop is moved in it hence, no current is induced. (Note that for induced current basic need is, change of flux)
