• Radio in Faraday Cage

• Wimshurst machine with large parallel plates and large black pith ball

•  video  - Parallel Plate Capacitor
  ( I'll want to use the dielectric insert too.)

• Ohm's Law
  ( Would it be possible to do this using batteries rather than a supply, and varying the number of batteries to change the voltage? I'll be in this afternoon to look at it.)

• Power Loss in Transmission Lines

• measure potential & current of a D-cell battery, initially across a 100 ohm resistor, then shorted

•  video  - Circuit Analysis

•  video  - RC Circuit w/ Function Generator
• RC Time Constant (DECAY)

•  video  - Magnetic Fields w/ Iron Filings
•  video  - Magnetic Fields w/ Matrix of Iron Rods
•  video  - Magnetic Fields Associated with Current Carrying Wires 1
•  video  - Force on a Current Carrying Wire in a Magnetic Field

• RC Time Constant (DECAY)

• "take a magnet for a walk" two strong magnets on rope attracting toward each other in air

•  video  - Magnetic Fields w/ Matrix of Iron Rods
•  video  - Magnetic Fields Associated with Current Carrying Wires 1
•  video  - Force on a Current Carrying Wire in a Magnetic Field

• Lorentz Force Tube & TV (video signal of clock) with magnet

•  video  - Magnetic Deflection of an Electron Beam
•  video  - e/m Tube Lorentz Force Demonstrator

• Loud Speaker Demonstrator
  (I'd also like the cut open speaker where you can see the magnet and the coil. )
•  video  - Galvanometer Movement
• Electric Motor

• Flash Bulb Coil
•  video  - LED Coil
•  video  - Jumping Ring

• microphone demo: large speaker wired to amplified speaker, back emf in motor demo: measure current draw of motor wired to power source, draws less current when there is little load (axle free to run), draws more current when there is a heavy load (axle is forced to slow down, induction demo: shake it flash light w/ coil, magnet, rectifier and LED
