I hope that I have chosen the correct thread and that this belongs here.
I understand the concept of a dipole, where you have opposite polarities at each end of a lineal object, i.e. a magnet. My question concerns the case of a sphere, where the outer surface is one polarity and the center is another, rather than a sphere that is merely 'half and half'. Considering that one pole is completely surrounded (enclosed) by the other pole, does this still count as a dipole, or does it now qualify as a monopole. Also, what are the criteria that would allow one to distinguish between different types (arrangements) of poles, to qualify as mono- vs di-? Thanks in advance for your help in enlightening me on this point. Gravitas
