A conducting loop of wire has an area of 150 cm2 and a resistance of 25.0 . There is a magnetic field of 100 T perpendicular to the loop.
 
  At what rate must this field be reduced to induce a current of 0.100 A in the loop?
  A)
 
  167 T/s
  B)
 
  60.0 T/s
  C)
 
  5.58 T/s
  D)
 
  0.354 T/s
  E)
 
  120 T/s

  f.
  B)
 
  4f.
  C)
 
  f/2.
  D)
 
  f/4.
  E)
