A non conducting sphere of radius R and uniform volume charge density is rotating with angular velocity, Omega. Assuming the center of the sphere is at the origin of the coordinate system, a) what is the magnitude and direction of the resulting magnetic field on the z axis for any arbitrary z distance away from the origin when z > R? b) same question as part a) but for z < R? Omega of the rotating sphere on the extra credit problem is also in the z direction.
