Two infinitely long straight and parallel wires carry current in opposite directions of 100 A. The wires are a distance 0.40 m apart and are aligned with the x-axis and lying in the x-y plane with the origin halfway between the two wires. The wire with the positive y-coordinate carries its current in the positive x-direction. Calculate the magnetic field vector at the origin, at (0, 0.1 m, 0), at (0, -0.1 m, 0) at (0, 0.3 m, 0), and at (0, -0.3 m, 0).
