P.11-3 A small filamentary rectangular loop of dimensions L, and L, lies in the xy-plane with its center at the origin and sides parallel to the x- and y-axes. The loop carries a current i(t) = I, cos wt. Assuming L, and L, to be much less than the wavelength, find the instan- taneous expressions for the following quantities at a point in the far zone: a) vector magnetic potential A, b) electric field intensity E, c) magnetic field intensity H.
