Answer to Question #192096 in Electricity and Magnetism for Ahmed

Question

In your electricity and magnetism lab, suppose you were enthusiastic to apply what
you learned about Faraday’s work and electromagnetic Induction. You decided to
uniformly charge the surface of a sphere of radius R with chare Q. Then you let the
sphere to revolve around the vertical axis with rotation velocity ω. With some
calculations you figured out that the magnetic field of such system should be as
follows: Inside the sphere,

Answer 1

Yes, the current will flow along the 'equator' of the sphere. and the magnetic field will induce inside the sphere. This is correct.
