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 2 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 0.278 m.
