Electric Field Demo for Van de Graafs
PRODUCT DETAILS
This device is designed to show the lines of electric field produced by a large electrostatic charge from a Van de Graaf Generator or Wimshurst Machine. It is easy to set up and yields excellent results which can be seen from the back row of class by placing it on an overhead projector. Fill the glass dish to about 5 mm with a layer of castor oil, then place between brass binding posts. Mount the single point electrodes just beneath the surface of the castor oil. When a fine sprinkling of iron filings are distributed on the surface and the terminals connected to a Van de Graaf Generator or Wimshurst Machine, the lines of force are clearly seen. Includes bottle of oil; transparent device suitable for use on an overhead projector, with plastic petri dish in center for holding oil; two parallel charge plates; two point charges; one round charge plate; and package of iron filings. Grades 6-12.
