A rectangular coil (0.20 m  0.80 m) has 200 turns and is in a uniform magnetic field of 0.30 T. When the orientation of the coil is varied through all possible positions, the maximum torque on the coil by magnetic forces is 0.080 N  m. What is the current in the coil?
 a. 5.0 mA
  b. 1.7 A
  c. 8.3 mA
  d. 1.0 A
  e. 42 mA

Question 2

A current of 4.0 A is maintained in a single circular loop having a circumference of 80 cm. An external magnetic field of 2.0 T is directed so that the angle between the field and the plane of the loop is 20. Determine the magnitude of the torque exerted on the loop by the magnetic forces acting upon it.
 a. 0.41 N  m
  b. 0.14 N  m
  c. 0.38 N  m
  d. 0.27 N  m
  e. 0.77 N  m
