A sphere made of (imperfectly) conducting and non-magnetizable (μr = 1) material is spinning in a homogeneous magnetic field. The magnetic field is parallel to the axis of rotation. Find the following steady-state quantities:
Assume that the equatorial velocity of the spinning sphere is not very large, i.e. v ≪ c, and use approximations. How could we improve the precision of the result?
You may want to review Chapter 3 in D. J. Griffiths: Introduction to Electrodynamics for help with some mathematical methods.
