 Franklin 1.8

An Electrostatic Field Tracer
for Macintosh Computers

Franklin 1.8 is a Universal Macintosh application for plotting electric field lines and equipotential surfaces around point charges. It is intended as freeware for science education. It is not however meant for commercial use or distribution without my permission.

The graphics seen at left were created in an earlier Mac OS 9 version of Franklin, then exported through the clipboard to the shareware program GraphicConverter where they were scaled to a much smaller size.

A few of my favorite links.
