A square loop of dimensions 2a x 2a lies in the xy plane with its center at the origin and sides parallel to the x and y axes. A counterclockwise current I runs around the loop.

Find the magnetic field on any point on the z-axis.

Compare the field at the center of the square loop with the field at the center of a circular loop of diameter 2a.
