Homework Answers
The center of the square is equidistant from the wires.
Thus, the currents wires must just add up to 0 with respect to the center of the square.
Thus,
-10 A - 8 A + 20 A + I = 0
--> I = 2 A [ANSWER, PART A]
To cancel all fields, it must be DOWNWARD. [ANSWER, PART
B]

2) A very large number of very long wires are arranged to form a current-carrying “ribbon," as shown in the figure below. Each wire can be assumed to have negligible radius and carries the same current I (in the same direction). The ribbon is oriented in the xy-plane, at z =0. Hint: This problem has planar symmetry, so consider how you might apply Ampere's Law. Also note that this problem is equivalent to an infinite current-carrying sheet with surface a...
