Python code for the animation of hysteretic transitions of a magnetic dipole cluster

An interactive Python program demonstrating the relaxation of the cluster described in the paper "Andrew D.P. Smith, Peter T. Haugen, Boyd F. Edwards: Hysteretic transition between states of a filled hexagonal magnetic dipole cluster, Journal of Magnetism and Magnetic Materials 549 (2022): 168991", and a related comment https://doi.org/10.48550/arXiv.2203.13670 . There a hysteretic transition between two stable arrangements of a cluster of seven dipoles is presented. The relative strength of the center dipole in a hexagonal arrangement serves as the bifurcation parameter. This experiment is great for classroom demonstrations, because it shows with its spontaneous symmetry breaking, the bi-stability, and the two different bifurcations leading to discontinuous jumps almost all of the elementary features of static nonlinear systems
