A straight 10-cm wire bent at its midpoint so as to form an angle of 90 carries a current of 10 A. It lies in the xy plane in a region where the magnetic field is in the positive z direction and has a constant magnitude of 3.0 mT. What is the magnitude of the magnetic force on this wire?
 a. 3.2 mN
  b. 2.1 mN
  c. 5.3 mN
  d. 4.2 mN
  e. 6.0 mN

Question 2

A circular coil (radius = 0.40 m) has 160 turns and is in a uniform magnetic field. When the orientation of the coil is varied through all possible positions, the maximum torque on the coil by magnetic forces is 0.16 N  m when the current in the coil is 4.0 mA. What is the magnitude of the magnetic field?
 a. 0.37 T
  b. 1.6 T
  c. 0.50 T
  d. 1.2 T
  e. 2.5 T
