How Can I Visualize Magnetic Fields?

[ortszentrum]

Hi,

I'd like to visualize magnetic fields between magnets and charges. Fieldlines/streamlines would be ideal but e.g. vector arrows would do too.
Although a 3D model would be perfect, any advice regarding 2D approaches is appreciated as well.

Do you have any tipps on how to accomplish this? Which languages/programs should be used best? Do you know of any examples/tutorials out there?

I have basic experience in OpenGL.

Thanks a lot,
Florian

There are some attempts linked off of the http://www.vpython.org page.
