[Visualpython-users] Field program

[Bruce S. <Bru...@nc...>]

Attached is a VPython program that is a useful lecture demo tool for 
displaying various aspects of electric and magnetic fields, which you 
might find interesting (and I'd appreciate critical comments if you play 
with it).

It is based on the features in a program "EM Field" by David Trowbridge 
and me, which won a national prize and has been distributed by Physics 
Academic Software. That program, which was written in the cT language 
(see the cT archives at vpython.org)  is showing its age, and in 
particular there isn't a Mac version that runs on OSX, nor a Linux 
version, so it seemed time to make a modern version. Ultimately it would 
be good to provide a 3D version of the Gauss's law visualization, but 
that's for the future.
