AI Thread Summary
A hollow ball can be shaped as a magnet, but its magnetic field will not be uniformly spherical, featuring at least a dipole moment. The behavior of such a magnet would depend on its magnetic field, which would not push or pull uniformly. Spinning a magnetic material of this shape would result in behavior similar to other magnets with comparable magnetic fields. If the inside of the hollow ball were more magnetic than the outside, it would not alter the magnetic interaction. Understanding these principles is essential for exploring magnetism in unconventional shapes.

TL;DR Summary
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.

No.
Thank you thank you
 

Thread 'Need help understanding particle physics and quantum physics'

So I know that electrons are fundamental, there's no 'material' that makes them up, it's like talking about a colour itself rather than a car or a flower. Now protons and neutrons and quarks and whatever other stuff is there fundamentally, I want someone to kind of teach me these, I have a lot of questions that books might not give the answer in the way I understand. Thanks
