Electromagnetics cause the most problems for the AP Physics C test out of all the material presented. The particles are just too small to see directly and therefore make hands on experiments out of the question. EM Demo is a program designed to help show EM concepts visually and as interactively as technology will allow.

You can find the online version here. Does not have as much control over configuration, however.

About the program:

The program works by animating flux so that the field feels more interactive. It also allows for space to predict  fields, making the simulation more exploration than just an animation.


Complex random configuration.


Flux lines of a dipole.


Flux lines of a complex system as well as regions of equipotential.

 

The package comes in both application form (pictured above) and an applet form which is less interactive but interesting all the same. You can download them from www.sourceforge.net/projects/emdemo.
