Exploratorium
Exploratorium: Science Snacks: Magnetic Pendulums
See how electricity and magnetism interact with this activity. Activity has students creating a current by swinging a copper coil through a magnetic field. The copper coil will start a second coil swinging as well.

Magnet Academy: Foucault's Disk
Leon Foucault, a French physicist much better known for his pendulum demonstrating the rotation of the Earth, also created in 1855 a device that illustrated how eddy currents work. (Java tutorial)

Magnet Academy: Inductive Pendulum
Get the swing of electromagnetic induction with this simple tutorial. (Java tutorial)
National High Magnetic Field Laboratory
Magnet Academy: Torsion Balance
Experiment with the torsion balance and see what happens first by giving the rod a charge, and then by moving the charged rod closer to the outer metal sphere of the instrument. Observe what happens to the needle as the charge increases.
