The two wires shown in the figure below are separated by d = 11.4 cm and carry currents of I = 4.95 A in opposite directions.
Two vertical, parallel wires are separated by a distance d. To the left of the left wire is an arrow labeled I pointing up. To the right of the right wire is an arrow labeled I pointing down. A point P2 is a distance 2d to the left of the left wire, and a point P1 is a distance d to the right of the right wire.
(a) Find the magnitude and direction of the net magnetic field at a point midway between the wires.
