Is it possible to model an electromagnetic energy harvester. The concept is similar to the piezoelectric energy harvester (https://www.comsol.com/model/piezoelectric-energy-harvester-21421) as in both are vibration energy harvester.
The main element is the spring/beam, magnet and coil. The basic idea is that body load (excitation) will be applied to the beam and the beam will move. The magnet on the beam will also move, so does the magnetic field around the magnet. The coil will capture the change in magnetic field and induce current in it.
The ouput expectation is the frequency response plot - relation between output voltage at the coil (x-axis) vs excitation frequency (y-axis).
I can simulate the magnetic field around the magnet using Magnetic Fields, No Currents (mfnc) physics in Stationary study. However, I cannot make the coil induce current / voltage from the magnetic field. I believe this require the Solid Mechanics (solid) and Magnetic Field (mf) physics and computed in the Frequency Domain study.
