As shown below, a square loop of wire of side a moves through a uniform magnetic field of magnitude B perpendicular to the page at constant velocity directed to the right. Which statement regarding the electric field induced in the wires is correct for the wires at the left and right sides of the loop?
 
   

   
  a.
  The electric field is directed upwards in both the right and left sides of the loop.
   
  b.
  The electric field is directed upwards in the right side and downwards in the left side of the loop.
   
  c.
  The electric field is directed upwards in the left side and downwards in the right side of the loop.
   
  d.
  The electric field is directed downwards in both the right and left sides of the loop.
   
  e.
  There is no electric field present in any side of the loop.

Question 2

As shown below, a square loop of wire of side a moves through a uniform magnetic field of magnitude B perpendicular to the page at constant velocity directed to the right. Judd says that the emf induced in the loop is zero. Roger claims that it has magnitude B. Which one, if either, is correct, and why?
 
   

   
  a.
  Judd, because the magnetic flux through the loop is constant.
   
  b.
  Roger, because the magnetic flux through the loop is constant.
   
  c.
  Judd, because the magnetic flux through the loop is not constant if .
   
  d.
  Roger, because the magnetic flux through the loop is not constant if .
   
  e.
  Roger, because the magnetic flux through the loop is _B = 0.
