Orientation of sphere magnet inside sphere magnet
magnO:
I am not planning to build anything. I came across this forum via another website that mentioned it, it used some models that it had found in this forum, and thought I'd ask about how the magnets in the example will orient themselves. Perhaps it is the wrong forum, or, maybe it is the right forum since it is people genuinely passionate about electricity.

Very interesting question magnO. Welcome to the Forum.
I think that the positive pole of the sphere inside will seek the negative pole of the outer sphere, as in the second picture.
Could this be corroborated using the FEMM program?

if you can provide a way to reference to that, would be great. If you cant provide a "link" until 20 posts. Reach out to MJ via PM and Im sure he can post the link. Just finished up my mac and cheese and going to bed now :)

nope, using guest mode in browser, no history record, so it is probably lost since I do not think I'll be able to remember specifically, I just followed the link to this forum

That is what I've thought as well, and I had an electrical engineer say the same thing, comparing it to a two-pole induction motor. I had someone else say the magnetic poles on the inside of a sphere would reverse that on the outside, so that the inner magnet would orient itself like in example 1 in the image above, that the inner sphere is like an inner extension of the outer one, i.e. they should both have the same pole orientation. So, since just one of those ideas can be true, I'm trying to sort out which one.
