An ac generator has 80 rectangular loops on its armature. Each loop is 12 cm long and 8 cm wide. The armature rotates at 1200 rpm about an axis parallel to the long side.
 
  If the loop rotates in a uniform magnetic field of 0.30 T, which is perpendicular to the axis of rotation, what will be the maximum output voltage of this generator?
  A)
 
  20 V
  B)
 
  27 V
  C)
 
  29 V
  D)
 
  33 V
  E)
 
  35 V

Question 2
