Orientation of sphere magnet inside sphere magnet
magnO:
I have now come up with a model that fits with the reason I asked the question, and that integrates with every single technical opinion given in this thread.
If example 1 is correct, because the surface on the inside diameter has a reverse polarity to the surface on the outside diameter, and an electric coil placed inside a non-magentised sphere induces a magnetic field with the same polarity on the outside (that model was the reason I asked the question), then the two objects will attract at the poles, the interior surface of the pole of the shell attracts to the pole of the coil, locking the objects to the rotational axis. The objects will at the same time repel at the equator, if I am correct (the field lines will run in opposite directions perpendicular to the equator. ) It would be good to have that last part validated or falsified, the rest has already been discussed I think in this thread, as this particular model conforms to example 1 which most opinions converged on.
So, the model actually seems to fit even tough the initial assumption was, it appears based on this thread, wrong.

The model I am thinking about (the reason I asked about orientation of concentric ring magnets) conforms to reverse poles on inside of hollow sphere magnets. Is that image showing reverse poles on inside of magnet, or something else?
magnO:
Hollow spherical magnet showing reverse poles on inside diameter, and magnet inside attracted to poles on inside surface of shell.
As that has been answered (I am very grateful for input from everyone who contributed), if anyone would like to contribute to the broader idea I work on, would the magnets repel at the equator? In schematics, the magnetic field lines flow in opposite directions in that region.
magnO:
The complete model,
Assumptions made, reverse poles on inside diameter of shell (seems to be consensus in this thread), electromagnetic induction with polarity in same direction (the shell treated like an extension of the inner magnet/coil), attraction at poles (locked to rotation axis), and repulsion at equator where field lines move in opposite directions.
Would be good to have last two assumptions (the induced polarity and repulsion at equator) validated or falsified.
