Simulation of Magnetic Domains

A large number of compass needles are mounted on a Plexiglass sheet. A bar magnet is used to set the needles in motion. When the needles come to a stop, interaction between the needles simulates magnetic domains.

Looks nice but its misleading. Alignment of magnetic dipoles is due to Heisenbergs exchange forces. This is quite the opposite of the classical force that causes dipole moments to become antiparallel.
