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.
