Description

Science First Electric Fields Apparatus bring out the lines of an electric field produced by a large electrostatic charge, such as that generated by a Van de Graaff Generator or Wimshurst machine. The unit measuring 6 x 8 x 2 inches contains electric field apparatus, iron filings, bottle of oil, two charged plates, two point charges and instructions. This transparent device is suitable for use on an overhead projector. Fill the dish with oil and mount your choice of electrodes just beneath the surface. Sprinkle iron filings and connect to show the patterns created. Great inspiration for a science fair project!
