Abstract

Both the hydrodynamic repulsive force between the disks and the central magnetic force acting on all disks were quantified. Two types of aggregates were considered: those in which one disk is much larger than the others and those in which two disks are larger than the rest. It was demonstrated that the self-assembly of spinning disks into macroscopic artificial atoms and molecules is the consequence of the interplay between attractive and repulsive interactions.
