one above the other
Two long, straight wires, one above the other, are separated by a distance 2a and are parallel to the x-axis. Let the y-axis be in the plane of the wires in the direction form the lower wire to the upper wire. Each wire carries current I in the +x-direction. What are the magnitude and direction of the net magnetic field of the two wires at a point in the plane of wires: (a) midway between them? (b) at a distance a above the upper wire? (c) at a distance a below the lower wire?
