Description: Wooden stand for standing on when using the Van de Graff generator. Rabbit fur, plastic rods, and glass rods for generating/storing charge.
Description: Useful for several electrostatic demonstrations. Rice crispies or Styrofoam peanuts placed on the dome will scatter from the electrostatic repulsion. Large sparks can be made with the discharge wand. A florescent light bulb tube will illuminate if brought near the dome.
setup time: < 10 minutes
Description: Demonstration of electrostatic shielding inside of a conductor.
setup time: < 10 minutes
Description: Ohm's law demonstration
setup time: < 5 minutes
Description: Discharge of a large capacitor. Typically discharged with the large (3 ft) screwdriver. Note: This capacitor stores significant energy and is dangerous. Replace aligator clips and shorting wire between the terminals when finished.
setup time: < 10 minutes
Description: Iron filings are suspended in a fluid. When a bar magnet is placed in the hole through the center of the cube, the magnetic field lines become visible. There is also a flat version of which works well on an overhead projector. Far left picture illustrates sheets of magnetic material that allow the visualization of field lines.
setup time: < 5 minutes
Description: Sprinkle iron filings on the plexiglass. Run current through the wires and the filings will align with the solenoid's field lines.
setup time: < 5 minutes
Description: A large current is briefly passed through the wire which is located between the poles of a strong permanent magnet. The current switch is a telegraph 'tap' switch. The current is supplied by a car battery which needs to be charged before use.
setup time: < 10 minutes
Description: An insulator, metal ring and metal ring with an small slit through it are swung through the strong magnetic field of a permanent magnet. Eddy currents in the metal ring noticeably change the motion through the magnetic field.
setup time: < 5 minutes
Description: A strong permanent magnet is dropped through a long copper tube. Eddy currents cause the magnet to fall slowly. A copper cylinder dropped through falls quickley. Either dropped through the tube with a slit in it fall at the same speed.
setup time: < 5 minutes
Description: AC power is applied to a coil in the base of the unit. A removable secondary coil with a bulb lights up when the current is applied. An aluminum loop will launch from the base because of the induced current in the loop. A split loop will not move.
setup time: < 5 minutes
Description: Use a magnet to deflect the electron beam in the tube. The electron beam is visible on the florescence coating on the inside of the front of the tube.
setup time: < 10 minutes
Description: Three arm rocket spins when charged by the Van de Graff
setup time: < 10 minutes
Description: Grasp the handles and flex the rod side to side. Sparks will appear between the two adjustable spikes.
setup time: < 5 minutes
Description: Touch charged objec to the appropriate top piece (rightmost equipment has a shield which must be removed first) and aindicator inside will move.
Description: Galvanometer measures current produced by the induced voltage when a magnet is moved into and out of a coil of wire.

Description: User configures circuit by changing the arranegment of the metal strips.
Description:
Description: Assorted cables hang from the demo room wall, various connectors are in the E&M section.
Description: Touch charged objec to the black circle and the needle will indicate.
Danger: The large Nd magnets are very strong, and can crush things between them (e.g. fingers).
Description: Coils with various connectors (bananna, BNC). Solenoid with iron core.
Description: Small breadboard also available.
Description: Small DC motors previously powered by AA batteries.
Description: Coils, each with screw-down or bananna connectors fit into one another to alter the current and voltage of the circuit.
Description: Various current, voltage, and resistance meters.
Description: Screw-down terminals. Slide the top to adjust the resistance .
