PHYS 2020: Principles of Physics II

• balloons to stick on the blackboard

•  video  - Attraction and Repulsion Between Charged Objects
  (In addition to 2x4, also I'd like to use that bigger prank, too.)
•  video  - Wimshurst Machine
  (to show )

•  video  - Attraction and Repulsion Between Charged Objects
  (In addition to 2x4, also I'd like to use that bigger plank, too.)
•  video  - Van de Graaff Generator
•  video  - Capacitor Discharge

• Ohm's Law
•  video  - Circuit Analysis

•  video  - Capacitor Discharge
•  video  - Magnetic Fields w/ Matrix of Iron Rods

•  video  - Magnetic Deflection of an Electron Beam
•  video  - Forces Between Current Carrying Wires
•  video  - Force on a Current Carrying Wire in a Magnetic Field
•  video  - Galvanometer Movement
•  video  - Back EMF in an Inductor
• Electric Motor

• Electromagnetic Can Crusher with big capacitor and fat coil - I may run out of time

•  video  - Back EMF in an Inductor
• 1x 2x 4x Coils and Bar Magnet
  ("Audience" camera)
•  video  - Hanging Ring and Magnet
• Flash Bulb Coil
•  video  - LED Coil
•  video  - Lenz's Law and Eddy Currents
•  video  - Eddy Current Tube
  ("Audience" camera / making sure that normal iron piece that is dropped for comparison is not magnetized )
• Hand Crank Generator
  (the one in the third picture)

•  video  - Jumping Ring
  (also the coil with light bulb to go with )
•  video  - Transformers

•  video  - Series LCR Circuit, Resonance
  (I want voltage scaled so I can show V_source = V_R + V_C + V_L. I want the following color coordination: V_source = RED; V_R = BLUE; V_C = GREEN; V_L = YELLOW. Last year's description says: "Use 100 ohm resistor instead of light bulb. Use shorts across L and C to show phase effects incrementally. Hide labels to scope channels and set scale to 2V. Set FG to 2000Hz, 6V")

•  video  - Series LCR Circuit, Resonance
•  video  - Polarization of Light
  (One polarizer on the projector, another polarizer held by a pincer above the projector about half a foot above. The third polarizer will be held by hand to insert in between.)
• Birefringence
• Polarization by Scattering
  (NOT THE ONE LISTED ON THE WEB! If you recall, we experimented last year with laser with water and a polarizer; camera shooting from above: the scattered light observed only at a right orientation of the polarizer.)

• big convex lens standing on bench, with a candle and its flame as object, candle movable across bench using a fixed camera to capture the image

  (on camera)
• Total Internal Reflection
  (used rectangle from ray optics kit)
