Question 2

A single circular (radius = R) loop of wire is located in the yz plane with its center at the origin. The loop has a clockwise current as seen from the point (+R, 0, 0). The direction of the magnetic field at the point
 a. (0, 0, 0) is i and at the point (+R, 0, 0) is i.
  b. (0, 0, 0) is i and at the point (0, +2R, 0) is i.
  c. (0, 0, 0) is +i and at the point (+R, 0, 0) is +i.
  d. (0, 0, 0) is +i and at the point (0, +2R, 0) is +i.
  e. None of the above
