I found several examples and a "book" describing the Magnetica Mathematica library.
However I can't find where to down load it.
I have searched on the web and "MagnetiaSoft" no longer seems to exist.
Is there an archive somewhere at Wolfram?
I'm actually looking for a tool to design solenoid magnets and perform design trades over parameters such
N - number of turns
B - field strength
D/L - diameter and length of the solenoid
both normal and superconducting magnets are of interest.
