Question

A semicircle conducting ring of radius R is placed in the xy plane, as shown in the figure. A uniform magnetic field is set up along the x–axis. No emf, will be induced in the ring. If

  1. it moves along the x–axis    
  2. it moves along the y–axis    
  3. it moves along the z-axis    
  4. it remains stationary    

The correct answer is: it moves along the x–axis
