Simulating magnets and magnetic moment

I am working on a project for an electricity and magnetism class that deals with using neodymium magnets to propel other neodymium in around a ring.  I was curious if anyone was aware of a method of both importing neodymium or any other rare earth magnetic material into Autodesk Inventor 2013 and then running a dynamic simulation on an assembly consisting of those parts.

Hi Patrick,

  Inventor Simulation (Dynamic Sim or Stress Analysis) doesn't have any electro-magnetic simulation functionality.

  You may be able to 'fake it' by using the input grapher to define a force function that is inversely proportional to the square of the distance between the "magnetic" bodies.  However, it would be tricky at best to account for the E-M field lines, etc.

  This topic has been touched upon here: http://forums.autodesk.com/t5/Autodesk-Inventor/Neodymium-Magnets/td-p/2361898

Hope this helps.  Please let us know if you have any additional questions, comments or suggestions.

Thanks, -Hugh

Thank you for the reply.  Are there any other Autodesk products that enable simulation with magnetic forces?

Hi Patrick,

  Autodesk Mechanical Simulation does have an electrostatics module.  Initially, I was just searching for magnetic in the product offering functionality page here: http://images.autodesk.com/adsk/files/simulation_mechanical_multiphysics_comparison_matrix_en.pdf

  You can search or ask for more specific info about whether the electrostatics functionality has what you're after in the MechSim forum here: http://forums.autodesk.com/t5/Autodesk-Simulation-Mechanical/bd-p/396

I hope this helps!

Best regards, -Hugh

Thank you again.  I think Multiphysics might just be the ticket!
