A Paper On The Mathematics Of These Animations
A Description of the TEAL/Studio Project at MIT (pdf file)
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 the fields by looking at the topology of the field lines. This is especially true when the field lines are animated. The examples given here are only a few of many (if you do not have a movie player, download QuickTime 3 to view both avi and quicktime files)
