Vibration analysis due to Magnetostriction

Please login with a confirmed email address before reporting spam

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,Magnetostrictionphenomenon will be observed, and eventually the core will vibrate. I want to analyzefrequency of vibrationof 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.
