I'm looking for software that allows visualistion (or calculation) of
magnetic field strength with arrays of "a few" permanent magnets.
There are numerous general electromagnetic field software packages
available, both free and for money, but they tend to be either too low
level or highly oriented towards complex electromagnetic applications
- and are also liable to have a reasonably significant learning
requirement.

What I want to be able to do is to specify magnetic 'strength' and
dimensions and then "push things around" to see what happens. A GUI
would be good but a numbers only solution would be OK as I can plot as
required.
Any ideas?

Yes, I've written something rough and ready myself but time per result
is not looking good. Somebody must have done this already.
