coupling solid mechanics with magnetic fields

Hello,

I'm currently trying to analyze the change of magnetic flux that is made by a 3D magnet that is adjusted on a periodically moving beam. (Physics: SOLID, MF and Time Dependent)

But unfortunately my simulation does not converge.

I checked all my BC (Boundary conditions) in order to have a unique solution and made a finer mesh, but it didn't help. I think I'm doing something wrong with the coupling between MF and SOLID Physics.

How can I couple these two physics in order to get the simulation work?

I would be really happy and thankful if someone can take a look at my model and help me out!
