A 2.0-cm length of wire centered on the origin carries a 20-A current directed in the positive y direction. Determine the magnetic field at the point x = 5.0 m on the x-axis.
 a. 1.6 nT in the negative z direction
  b. 1.6 nT in the positive z direction
  c. 2.4 nT in the negative z direction
  d. 2.4 nT in the negative z direction
  e. None of the above

Question 2

An unusual lightning strike has a vertical portion with a current of -400 A downwards. The Earth's magnetic field at that location is parallel to the ground and has a magnitude of 30 mT. In N, the force exerted by the Earth's magnetic field on the 25 m-long current is
 a. 0.
  b. 0.012 N, East.
  c. 0.012 N, West.
  d. 0.30 N, West.
  e. 300 N, East.
