Greetings, I want to understand magnetic bearings better , i used google search but couldn't find a simple and satisfying picture or diagram.
Could someone please explain the very basics? I would prefer in terms of permanent magnets rather than electromagnets because that would simplify the picture.

If we have a rotating shaft and a so called sator does the shaft and stator has to be aligned with the same poles of magnets in a symmetrical way so hat each stator pole would push equally from all sides and the rotor shaft would saty right in the middle or what?

thank you.

Anyone , please?
 
hahaha didn't know that LOL
