- montecarl 3y agoOn an array of magnets, but not on a single magnet.
- jamesakirk 3y agoGood point.
- po 3y agoTrue, but only trapped within alternating N/S permanent magnetic poles... so it's possible to fool other people, but you won't be fooled yourself. Just don't use that magnetic setup. Superconducting materials will levitate in the field of a single magnetic pole.
- kadoban 3y agoNot on a single magnet though, it has to be a shaped array.
