# Simulator for electrostatics

I am searching for a tool that visualizes the electric field/potential for simple electrostatic configurations like

• conducting/polarized sphere in an uniform electric field
• conducting/polarized sphere in a field generated by some simple charge density (like e.g. finite line charge)

I did a search on the internet but did not find anything useful. Does someone know such a tool (preferably for Linux). Thanks a lot.

I've used Paul Falstad's applets for classes I've taught. He has some very impressive visualizations there including some that you don't see often (like the magnetic vector potential). He always links to the Java source code, so if you can program, it'll give you a good base to start with.

Check out http://www.falstad.com/vector3de/ for an example.

There are lot of visualizations available on mathematica demonstration site.
