Consider the diagram below showing 2 two current loops (a square and circle centered about the same point. If the currents in each loop are in opposite directions and the current in the square loop is 3.13 A, what must the current in the circular loop be if the net magnetic field at the center is zero? Let the radius of the circle be 0.146 m.
