suppose that there is a metallic ball inside a magnetic sphere. could the ball be suspended in the middle of the inside of the sphere if the inside of the sphere had a uniform polarity?

It's been done. Gainsville Magnetic Lab University of Florida.

The magnetic field in the center of the sphere would be close to zero and the ball position would follow the rules of the outside gravity.
If you where talking about a body in the center of the Earth, then the body would be suspended.

Well it depends is the metal in question a ferous metal. You could cause the ball to be suspended if you used magnets or superconductors. There could be other ways to achieve it. But from my grasp of physics, polarity could produce a magnetic force. I don't know those are my thoughts.

In theory YES!
Practically, how would you know? You can't look inside this thing. Schroedinger got mad about this delima.
But there are a lot of magnetic gadgets suspending things in mid air.
