A long straight wire is parallel to one edge and is in the plane of a single-turn rectangular loop as shown. If the loop is changing width so that the distance x changes at a constant rate of 4.0 cm/s, what is the magnitude of the emf induced in the loop at an instant when x = 6.0 cm? Let a = 2.0 cm, b = 1.2 m, and I = 30 A.
 
   

   
  a.
  5.3 V
   
  b.
  2.4 V
   
  c.
  4.8 V
   
  d.
  2.6 V
   
  e.
  1.3 V

Question 2

A loop of wire (resistance = 2.0 m) is positioned as shown with respect to a long wire which carries a current. If d = 1.0 cm, D = 6.0 cm, and L = 1.5 m, what current is induced in the loop at an instant when the current in the wire is increasing at a rate of 100 A/s?
 
   

   
  a.
  34 mA
   
  b.
  30 mA
   
  c.
  27 mA
   
  d.
  38 mA
   
  e.
  0.50 mA
