Problem Statement: There is a core (Ferromagnetic/Steel) placed horizontally with one end fixed and other end free. A coil is wounded on the core, and given AC supply to it. Due to alternating flux generation in core, Magnetostriction phenomenon will be observed, and eventually the core will vibrate. I want to analyze frequency of vibration of the core.

I am new to COMSOL. Can someone please help me out to simulate this problem statement, any references, examples? Thanks in Advance !!

There is at least one example in the application library that comes with COMSOL.

The model that Edgar is thinking about is probably Piezomagnetic Cell Rover.
