Does a Magnetic Soccer Ball Carry Toroidal Moment? – An App to Examine 551 Dipole Clusters

The dipole-dipole interaction is a substantial part of the force that holds matter together. Since the electric and magnetic dipole-dipole interactions are mathematically equivalent, this fundamental interaction can be experimentally examined with magnetic spheres. For a numerical investigation the software package “dipole_clusters.py” allows an interactive examination of the

• dipole arrangement,
• field,
• binding energy,
• mutual interaction

of more than 500 of such clusters.

The "soccer championship" version 2.0 

• adds all Archimedean soids
• provides a technically interesting Halbach modification as starting configuration
• is – together with the complete Python script – also available as an exe-file.
