Two long, parallel wires are separated by a distance and carry current flowing in opposite directions, as shown in the figure. A circuit segment of length is parallel to the long wires and carries a current of ′ flowing in the direction shown. The circuit segment is at distance from the wires. The + direction is to the right, the + direction is up, and the + direction is out of the screen. Approximate the net magnetic force ⃗ B,net acting on the circuit segment in terms of the given quantities and physical constants assuming that ≫. Express the force using unit vector notation.
