Two long, straight wires, one above the other, are seperated 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 from the lower wire to the upper wire. Each wire carries current I in the +x−direction. Find B⃗  - the net magnetic field of the two wires at the following points in the plane of the wires.

a) Midway between the wires. Express your answers in terms of the variables I, a, and magnetic constant μ0.

b) At a distance a above the upper wire. Express your answers in terms of the variables I, a, and magnetic constant μ0.

c) At a distance a below the lower wire. Express your answers in terms of the variables I, a, and magnetic constant μ0.
