Each of two parallel wires separated by 8.0 mm carries a 20-A current. These two currents are oppositely directed. Determine the magnitude of the magnetic field at a point that is 5.0 mm from each of the wires.
 a. 2.0 mT
  b. 1.6 mT
  c. 1.3 mT
  d. 1.8 mT
  e. 1.0 mT

Question 2

Two very long parallel wires carry currents in the positive x direction. One wire (current = 15 A) is coincident with the x axis. The other wire (current = 50 A) passes through the point (0, 4.0 mm, 0). What is the magnitude of the magnetic field at the point (0, 0, 3.0 mm)?
 a. 3.8 mT
  b. 2.7 mT
  c. 2.9 mT
  d. 3.0 mT
  e. 0.6 mT
