I wonder if somebody would give me help with a problem I've been thinking about. Just as a thought experiment, one could imagine this. Suppose there was a world of 2D beings living on the inside of a rotating cylinder, with the cyclinder being made out of some rubbery substance. I think they could experience something like gravity, because massive objects would, due to centripetal force, make "dents" in the cylinder, and other nearby objects would be attracted to one another.
Now I've been thinking about this. Is there any way that one could create a mechanical system that would replicate the way EM works, i.e. with like poles repulsing one another and unlike poles attracting one another? I'm trying to think of this specifically with some form of rotation, but if there are other models, I'd be happy to hear.
