Re: e-field software?

Physics Academic Software's EM Field program is pretty good at
drawing E and B field lines and I believe it comes on both platforms.
It is not, however, free or even cheap -- $140/copy.

Today in lecture someone asked me to draw a few more magnetic field
lines on the diagram I was making (two wires carrying parallel
currents coming straight out at you). I was sufficiently unconfident
of my ability to produce such a drawing without seriously
misleading them that I declined to do so, stating that reason. What
is needed, of course, is a program which will allow one to draw many
more field lines than are usually drawn in the figures that appear
in textbooks.
