Xenophon, Anabasis, IV.7 (1) Consider a circular loop of radius R which lies in the x y plane. Suppose that the loop carries a current I directed counterclockwise as viewed from above. a) Write an explicit integral expression for the x component of the magnetic field at position vector r = (0 , y, z ). (10 points) b) Write an explicit integral expression for the y component of the magnetic field at position vector r = (0 , y, z ). (10 points) c) Write an explicit integral expression for the z component of the magnetic field at position vector r = (0 , y, z ). (10 points) d) Evaluate the integral for B x in part a). If you could not get the integral at least evaluate the leading multipole contribution to the x component. (5 points) (2) Consider a spherical shell of radius...
