A long straight wire runs in the +y or -y direction on the y axis. In the x-y plane, there is a wire wound 10 times with a radius of 0.6 meters with a current. The center of the wire is located at x = +2.0 m, y = +0.9 m and it's magnetic moment is 2.2 A m2 in the +z direction. If the total magnetic field due to the wire on the y axis and the circular wire is 4 x 10-7 T in the -z direction at the center of the circular wire, what is the amount, in amps, and the direction of the current on y axis? If in -y direction, indicate so with a negative sign.
