Abstracts

EN

Using video tracking we study configurational and melting properties of a finite number (64) of 6 mm sized disc magnets moving on an air layer produced by an air table to imitate two-dimensional (2D) crystal. It is shown that velocity of air flow allows us to influence temperature. Analysing trajectories of particles has shown the transition from hexagonal to square lattice and after it to liquid phase with underlying square shell structure.
