Total charge is uniformly distributed on a spherical surface of radius R. The sphere is centered at the origin and spins around
the z axis with angular velocity 0. Assume magnetic permeability u, everywhere. (a) Show that away from the spherical surface, the magnetic field can be expressed as H=-V Oy, with Voy=0 .(b) Find the surface current density K and the boundary conditions for the magnetic induction B at r=R. (C) Find y inside and outside of the sphere. (d) Find B inside the sphere.
