I am working on a complex configuration of magnets and every time I make an experiment something unforseen happens. Now I believe I could speed up the development by sitting down and calculating the configuration in all scenarios. My question is however: Is there any software that can help me to calculate the forces between magnets. I am already working with AutoDesk as my CAD software.

If you are interested in the force on a complex configuration of magnets, you most likely will need a 3D electromagnetics FEM solver, something like Ansoft Maxwell 3D, Opera 3D, or other comparable software packages.

My magnets are passive/static magnets, but maybe I can still use the packages? –  David Jan 14 '11 at 20:10

Yes, these software packages handle magnetostatics with no issue, including permanent magnets, and electromagnets. –  stl_piznaul Jan 14 '11 at 20:13
    
Thank you very much for this! –  David Jan 14 '11 at 20:48

Please look to Yonnet, Helm Janssen and Compter. Analytical equations for forces are available and sometimes even torque is included.
