Hi,
I am trying to model an electromagnetic acoustic transducer which involves three physical phenomenon: The static magnetic field generated by the horse shoe magnetc, the dynamic magnetic field generated by a coil driven by a sinusoidal current, and the solid mechanics which generatecs the sound wave on the material (steel).
The sound is wave is generated as a result of the interact of the induced current and the magnetic field generated by both the magnet and the coil.

Question:

1. the model could not couple the structural mechanics, what can i do to couple the three physics.

Please see attched my model.

Could you solve this? I could share a simulation with the same problem.
thanks
