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 'Why can't Solar panels be hemispherical, or a curved strip type?'

comparing a flat solar panel of area 2π r² and a hemisphere of the same area, the hemispherical solar panel would only occupy the area π r² of while the flat panel would occupy an entire 2π r² of land. wouldn't the hemispherical version have the same area of panel exposed to the sun, occupy less land space and can therefore increase the number of panels one land can have fitted? this would increase the power output proportionally as well. when I searched it up I wasn't satisfied with...

Thread 'The Physics of unloading sand from a barge'

I think it's easist first to watch a short vidio clip I find these videos very relaxing to watch .. I got to thinking is this being done in the most efficient way? The sand has to be suspended in the water to move it to the outlet ... The faster the water , the more turbulance and the sand stays suspended, so it seems to me the rule of thumb is the hose be aimed towards the outlet at all times .. Many times the workers hit the sand directly which will greatly reduce the water...
