    This content was COPIED from BrainMass.com - View the original, and get the already-completed solution here!

    A square of edge 'a' lies in the xy plane with the origin at its center. Find the value of the magnetic induction at any point on the z axis when a current I' circulates around the square. Show that your result gives the value 2(sqrt 2) Uo*I' /pi*a or the induction at the center. See attachment for better formula representation.
