You can stably suspend graphite pencil lead on permanent magnetic fields. E.G.: https://www.youtube.com/watch?v=yeIizmhzPQc

True, 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.

On an array of magnets, but not on a single magnet.

Good point.

Not on a single magnet though, it has to be a shaped array.
