Given a circular loop of radius a and carrying current I, its axis being coincident with the x coordinate axis and its center being at the origin. a) Use the divergence property of the magnetic induction, find the space rate of change of the of By with respect to y. b) From (a), write an approximate formula for Ey, valid for small enough values of y. c) Find the magnetic force, due to the field of the loop in the preceding part, on a second circular loop coaxial with the first, having its center at x=L. This loop carries current I' in the same sense as the other, and has a radius sufficiently small that the approximate field By of the preceding part is valid.
