A set of wires arranged on the corners of a square of side
lengths each carry a different current, as shown in the figure.
The wire in the lower left corner carries a constant current I
in the k-direction. The wire in the upper left corner carries a
current ₁ = −1k, the wire in the upper right corner carries
a current 12 = -81k, and the lower right wire carries a
current 13
=
31
