The tractor beam effect could be from the black phosphorus impurities in the sample. That's ferromagnetic so you have two kinds of forces on the flake. Earlier I joked to my friend that this Beijing expert doesn't understand what he was seeing and we shouldn't laugh at his predicament.. an x-ray of his sample probably showed that there wasn't a lot of lk99.
