  1. A positive charge is moving along the x-axis in the positivedirection. What is the direction of the magnetic field on they-axis?
  2. A long straight wire lies along the y-axis carrying current inthe positive y direction.What is the direction of the magneticfield at x = 3m, y = 3 m?  What is the direction of themagnetic field at x = -3m, y = 3 m?
  3. A wire extends from x = - ∞ to x = 0 on the x-axis, then turnsand extends from y = 0 to y = ∞ on the y-axis. The direction of thecurrent is in the positive direction.  What is thedirection of the magnetic field at x = 5 m, y = 0m?
