Buckling and zipping of a magnetic ring under gravity

Key Points

Flattening occurs in magnetic rings as bead density increases, leading to a stable zipping state.
Key findings include the observation of scaling laws during zipping transitions in the experiments.
Theoretical modeling and simulations support the experimental results, providing insights into the system's behavior.
Results imply potential applications in material design, emphasizing the physical interactions of flexible assemblies.

Abstract

Ring-shaped assemblies of magnetic beads behave similarly to a flexible, elastic annulus. In this paper, the authors perform a tabletop experiment with rings under gravity and report that initially circular rings experience flattening as the number of magnetic beads grows, until they reach a zipping state, where opposite sites stick together. The experiments are supported by a theoretical model and simulations that predict the observed scaling laws.#TheoryExperiment #ClearMotivation #BroadlyAccessible
