A set of wires arranged on the corners of a square of side length ? each carry a different current, as shown in the figure. The wire in the lower left corner carries a constant current ? in the ?-direction. The wire in the upper left corner carries a current ?⃗1=−??, the wire in the upper right corner carries a current ?⃗2=−10??, and the lower right wire carries a current ?⃗3=?2?. Determine the vector expression for the net magnetic force ?B→ per unit length ? on the lower left wire using ??? unit vector notation. Express your answer in terms of the permeability ?0 of free space, ?, ?, and numerical constants.
