Q1/A constant surface current = ko flows on the surface of a sphere with radius R. 1. Directly use the Biot-Savart to fined the magnetic field H at the center of the sphere. If the uniform volume current ] = Jo (A/m) though all of the sphere also fined the magnetic field H at the center of the sphere. 2. Using the above currents, find the magnetic dipole moments. In the case of surface current density, determine the magnetic scalar potential inside and outside. Use the magnetic field result in part (a).
