Assume the wire visible in the plane is bent perpendicularly at A and at C, with the remainder of the wire behind the paper. A current of 4 A flows toward you at A, through the visible portion, and back in the opposite direction at C. Consider the wires below the plane at A and C to be semi-infinite. There is a magnetic field of strength 9.9 T into the paper (not including the field due to the current in the wire). What is the magnitude of the force on the wire due to the external magnetic field B? It may be necessary to take into account the contribution from the long straight wire which runs up to and down from the underneath side of the page. The permeability of free space is $1.25664 \times 10^{-6} \text{ T} \cdot \text{m/A}$. Answer in units of N.
