Experimental analysis reveals that magnetic shaking controls granular dynamics in microgravity, indicating potential in space technology applications.
This study investigates the dynamics of granular particles agitated by magnetic shaking within a drop tower setup. We analyze the experimental images showing approximately 450 spherical magnetic particles with a diameter of 1.6 mm in a 60 mm spherical sample cell. We find that the magnetic excitation leads to a uniform spatial distribution of both particle positions and velocities. This demonstrates the effectiveness of magnetic shaking as a method for controlling granular systems in microgravity environments, with potential applications in material science and space technology.
