5B10.70 - Potential Field Model

Code Number:
Demo Title:
Potential Field Model
Electric Fields
Area of Study:
Electricity & Magnetism
Hula Hoop with Stretched Spandex, Plexiglas Stakes, Ping Pong and Steel Balls, and Marbles.

Screw one of the leg assemblies into the table for stability.  When ready, place the stakes upright under the Spandex in the potential field pattern you desire.  The balls may be used to show how a particle will act within or on the contours of the field you have made.
