SUMMARY

A hollow ball can be shaped as a magnet, but its magnetic field will not exhibit spherical symmetry, possessing at least a dipole moment and potentially higher moments. When considering the behavior of such a magnet, it will not pull or push in a conventional manner due to its unique field configuration. Spinning a magnetic material of this shape will yield behavior consistent with other magnets that have similar magnetic fields. If the interior of the hollow ball is more magnetic than the exterior, it does not alter the fundamental magnetic interactions.

PREREQUISITES
  • Understanding of magnetic fields and dipole moments
  • Basic knowledge of magnetism and magnetic materials
  • Familiarity with the principles of magnetic symmetry
  • Concepts of rotational dynamics in magnetic materials
NEXT STEPS
  • Research the properties of dipole moments in magnetism
  • Explore the effects of magnetic field symmetry on magnet behavior
  • Learn about the dynamics of spinning magnetic materials
  • Investigate advanced magnetic configurations and their applications
USEFUL FOR

Physics students, materials scientists, and engineers interested in magnetism and magnetic field applications.

TL;DR
One is it possible and multiple questions based on it (if it's not then the other questions are void)
I want to start this post by saying I don't know much and I'm asking everything here so I don't fill the forum with a million questions. I apologize if this is not how it is done.
My questions are...

Is it possible for a magnet to be in the shape of a hollow ball?1. Would it pull? push? or neither?

2. What happens if you spin a magnetic material of this shape?

3. If the inside were somehow more magnetic than the outside would it change the answer to question 1?

It is possible for a magnet to be in the shape of a hollow ball, but its magnetic field will not be spherically symmetric. It will have, at least, a dipole moment and possibly higher moments.

It would behave the same as other magnets with similar magnetic fields.
