1. The problem statement, all variables and given/known data Is it possible to design a current winding that will produce a uniform magnetic field in a spherical region of space? 2. Relevant equations Well, the literature tells that the equation for the B-field for a uniformly magnetized sphere = (2/3)u_0 * M and also the magnetization current density = J = curlM may be helpful. 3. The attempt at a solution The truth is that I don't even have a clue where to begin or how to think. Really need some help on this one.
