Dynamic problems in magnetic fields

Please login with a confirmed email address before reporting spam

A box filled with liquid, the liquid will not flow, and there are short fibers that can be magnetized. Now I want to use an external magnetic field to make the short fibers rotate, and see how large the moment is when the short fibers rotate. And also wanna know how strong the externally applied magnetic field is. I have now successfully simulated the external magnetic field in the AC / DC module and can calculate the torque on the short fiber, but I have not found a similar dynamic problem in the ac / dc case library, which is the module for this problem? Will the fluid CFD module be involved? Or is there a similar example for comsol?
