Question

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 induction B constant in time and space, pointing perpendicular and into the plane of the loop exists everywhere. The current induced in the loop is

  1. fraction numerator B l v over denominator R end fractionclockwise    
  2. fraction numerator B l v over denominator R end fractionanticlockwise    
  3. fraction numerator 2 B l v over denominator R end fractionanticlockwise    
  4. Zero    

The correct answer is: Zero


    No flux change is taking place because magnetic field exists everywhere and is constant in time and space.
