Point P is midway between two long, straight,
parallel wires that run north-south in a horizontal plane. The
distance between the wires is 2.1 cm. The wire on the
west carries a current of 2.0 A toward the north,
and the wire on the east side carries the same amount of current
but runs toward the south instead. Find the magnitude and
direction of the magnetic field at point P.
