A rectangular loop of wire has a length 2a in the x direction and a width 2b in the y direction. The loop lies in the z = 0 plane and is centered at the origin. Assuming that the loop carries a current of I Amps counterclockwise, as viewed from the positive z axis, find the magnetic field vector H at the center of the loop.
Hint: Consider how the contributions from opposite sides of the rectangle compare, to save yourself some time.

A rectangular loop of wire lies in the xy-plane. One corner of the loop is at the origin. The loop is 3.0 cm × 2.0 cm so the opposite corner is at x = 3.0 cm, y = 2.0 cm. The magnetic field in this region is non-uniform. The magnetic field for x < 2.0 cm is 3.0 T in the positive z-direction and the magnetic field for x ≥ 2.0 cm is 2.0 T in the negative z-direction. Find...
