Three currents i1100 a is on a circle of radius 100 m in

Question

Three currents, I₁=1.00 A is on a circle of radius 1.00 m in the xy plane, going clockwise, centered at the origin of the coordinates, I₂=3.00 A is a line current, coming out the xy plane, on the x axis at x₂=3.00 m, and I₃=2.00 A is a line current, going into the xy plane, on the y axis at y₃=2.00 m. Find the magnitude of the magnetic field at the origin of the coordinates.
