PIRA 5A40.50 Induced Charge: Franklin Bell
Photo Shows the Demonstration Apparatus Used by the University
of Texas at Austin
Concepts Conveyed:
Safety:
- When the demo is finished, touch the two electrodes together to discharge any remaining
charge before touching any metal.
Instructions / Notes:
- Once the weight is still, crank the Wimshurst machine until the weight begins to oscillate
between the two electrodes.
Demo Staff:
- Put the stand next to the Wimshurst machine, and make sure the weight is between the
two electrodes.
- The string has a red line to mark the proper height the weight should hang from. If the
weight is at the proper height and then positioned equally between the electrodes, the
weight should oscillate properly.
