Four very long wires are directed perpendicular to the plane of Figure P20.82. The points where these wires cross the plane of the drawing form a square of edge length 0.45 m, and each wire carries a current of magnitude 2.5 A. Find the magnetic field at the center of the square (i.e., at the origin).
