Two long straight wires carry currents perpendicular to the xy plane. One carries a current of 50 A and passes through the point x = 5.0 cm on the x axis. The second wire has a current of 80 A and passes through the point y = 4.0 cm on the y axis. What is the magnitude of the resulting magnetic field at the origin?
 a. 200 mT
  b. 600 mT
  c. 450 mT
  d. 300 mT
  e. 400 mT

Question 2

Two long parallel wires carry unequal currents in the same direction. The ratio of the currents is 3 to 1 . The magnitude of the magnetic field at a point in the plane of the wires and 10 cm from each wire is 4.0 mT. What is the larger of the two currents?
 a. 5.3 A
  b. 3.8 A
  c. 4.5 A
  d. 3.0 A
  e. 0.5 A
