A current of 5 A flows to the right along the x-axis through an infinitely long wire. A loop of wire with radius 25 cm is centered along the y-axis at y=1 meter. It has a clockwise current of 1 A. A second straight wire with a current of 10 A upward is parallel to the y-axis. (I of long wire1 = 5A; I of loop wire= 1A clockwise; r of loop = 0.25m; I of long wire2= 10A)
a) How far away from the y-axis should the second wire be so that the B-field at the center of the loop is zero?
b) Draw the final arrangement of wires?
