PHYS 2020-001: Principles of Physics II

• Big Faraday Cage Demo (Please instruct)

•  video  - Kinds of Charge and Charging
  (instead of pith balls, balloon electroscope hung from ceiling w/ fishing line / Probably better to set a camera on the electroscope to project on the screen.)
•  video  - Attraction and Repulsion Between Charged Objects
  (In addition to 2x4, also I'd like to use that bigger prank, too. )

•  video  - Capacitor Discharge
• Ohm's Law
•  video  - Circuit Analysis

•  video  - Magnetic Fields w/ Matrix of Iron Rods
  (on camera or on overhead projector )
•  video  - Magnetic Deflection of an Electron Beam
  (on camera )

•  video  - Magnetic Fields Associated with Current Carrying Wires 1
  (on overhead projector )
•  video  - Forces Between Current Carrying Wires
  (on camera )
•  video  - Force on a Current Carrying Wire in a Magnetic Field
  (on camera )
•  video  - Galvanometer Movement
  (on camera )
•  video  - Back EMF in an Inductor
  (the gigantic electro-magnet with an iron-bar (to show how the stuff becomes magnetic, not for the purpose of back EMF )
• Electric Motor

  (w liquid nitrogen )
• Hand Crank Generator
  (with removable light bulb )

• electromagnetic coke-can crusher

•  video  - Transformers

•  video  - Series LCR Circuit, Resonance
  (I want all voltages 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. )

• Corn syrup curved refraction in a fish tank (with a mirror at the bottom to reflect would be a nice addition) for Monday July 30th

•  video  - Polarization of Light
  (One polarizer on the projector, another polarizer held by a pincer above the projector about half a foot above. ( Third polarizer will be held by hand to insert in between.) )
• Birefringence

•  video  - Ray Optics Kit
  ( on camera )
• Concave Mirror
  (with a candle (and matches/lighter to light up); no need of lamp/box; can camera capture the image? )

  (on camera )

• Big convex lens standing on a desk, with a candle light as object

  camera on the desk movable across the desk to capture the image (I did this last fall in phys 2415)
