Circular surface current distribution, symbolic integration. There is a surface current over a circular surface of radius b with a hole of radius a (a < b) in free space. The surface lies in the plane z = 0 of a cylindrical coordinate system, with the coordinate origin coinciding with the surface center. The surface current density vector [see Fig.3.1(b)] plot the distribution of the resultant magnetic flux density along the z-axis, for −a ≤ z ≤ a. (ME4 10.m on IR) H
