Michael Faraday was the first to realize that the shape of electromagnetic field lines is extraordinarily expressive of their dynamical effects. We can understand intuitively many things about the forces transmitted by...

This site, created by William Beaty of Eskimo.com, has all the information needed to understand the operation and maintenance of Van de Graaf generators. The site explains the Van de Graaf generator, tips on building...

This Java applet was designed to enhance understanding of electric field lines. By "drawing" lines from simulated charges on a color-coded field, the learner can explore vector field diagrams and form concepts about...

This page, authored and curated by David P. Stern, illustrates the concept of work against an electric force using the examples of the Van de Graaff generator and lightening. There are also shorter examples of the Xerox...
