The Van de Graaff generator and it's grounding device can be used to show discharge of static electricity.

Fur is used to charge a rod, which then deflects an electron beam

A capacitor is charged using a 9V battery.  The capacitor is then discharged through a small light bulb.

Pie placed on top of a Van de Graaff generator fly off when the machine is turned on.

A lightning rod is used to draw electric charge from Van de Graaff and prevent discharge

Grass seeds are sprinkled into a plexiglass container of castor oil that has 2 electrodes.  When voltage is applied across the electrodes, the seeds (dipoles) will align to show the electric field.  The image is projected using an overhead projector onto the wall of the lecture hall.

A handheld radio is placed inside a cage made of copper wire mesh.  The signal ceases to be heard.

The variable capacitor is used with the Van der Graaf generator to demonstrate dielectrics in electric fields

Weights dropped from a height of 1 meter provide an audible measure of the amount of energy stored in each capacitor available for display.

Discharge from a Van de Graaff machine lights a fluorescent light bulb.

A small magnet is passed through a coil of wire connected to a voltmeter.  As the magnet passes through the coil, a spike can be read on the meter, showing that current has been created.

A small, hand-held generator lights an LED by turning a crank.

Turning the crank of a motor lights 3 bulbs.

Different materials are used to show the ability of a magnetic field to penetrate through to the nails on the other side.

One magnet floats above another due to repulsive forces.

A magnet is broken to show that 2 magnets are created, not 2 disconnected poles

Device that shows the angle of Earth's Magnetic Field

Current flows through two parallel wires.  The current flows in either the same direction or different directions to produce attraction or repulsion, respectively.
