If you have a bunch of magnets lying around have a look at Halbach arrays.
Wow; I knew something like this was possible since we've all held refrigerator magnets and such that obviously had oddly arranged fields, but I only had the vaguest idea. Thank you.
Halbach arrays and some correction coils can be used to make a passive magnetic bearing (long sought after holy grail). They are super interesting.
I've seen that a few years ago, for denser motors. Do they have any other use ?
Thanks for the suggestion nonetheless
