A square loop (L = 0.20 m) consists of 50 closely wrapped turns, each carrying a current of 0.50 A. The loop is oriented as shown in a uniform magnetic field of 0.40 T directed in the positive y direction. What is the magnitude of the torque on the loop?
 
   


   
  a.
  0.21 N  m
   
  b.
  0.20 N  m
   
  c.
  0.35 N  m
   
  d.
  0.12 N  m
   
  e.
  1.73 N  m

Question 2

A wire (mass = 50 g, length = 40 cm) is suspended horizontally by two vertical wires which conduct a current I = 8.0 A, as shown in the figure. The magnetic field in the region is into the paper and has a magnitude of 60 mT. What is the tension in either wire?
 
   


   
  a.
  0.15 N
   
  b.
  0.68 N
