Does the charge move generating current, per "Right Hand Rule" ? Does the magnetic field concentrate the charge around the equator ?
Does the charge and field remain stationary as the sphere spins ?
Doesnt help identify what the field is ? Just musings.....

The spinning sphere has to be spinning against either in opposition to another spinning conductor or that conductor has to be stationary. That's how you get charges to move and that, by extension, builds up a magnetic fields. This is important in planets, because a metalic core is required for a metalic field to shield that planet from charged particles and certain radiation [alpha and beta radiation]. So we can see how the field is created, but not what compses that field specifically.
