Have you ever seen an electromagnetic chain? Its a series of electric and magnetic toroid cores linked in the form of a chain transferring power from electricity to magnetism and back again as it works it way along the device. Its a great hands-on illustration of Maxwell's equations as well as an illustration of transformer action taken to extremes.
Watch a soda can rip itself apart in a fiery explosion at 11,000fps with a Phantom high speed camera. Running a current through a coil, produces an electromagnet.
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.
