Hi,
I'm trying to model an electromagnetic energy harvester using as model the example COMSOL provides for induced voltage in a coil due to a moving magnet (https://www.comsol.com/model/voltage-induced-in-a-coil-by-a-moving-magnet-14163). Here the movement of the magnet is made through a moving mesh and a sinusoidal function.
I want to expand the model where the magnet oscillates due to an applied force and the oscillation are damped due to magnetic and mechanical damping of the spring of which the magnet hangs.
I think this can be made modeling the whole as a spring mass system. However I don't know much about the solid mechanics physics and i can't find an example that shows how to a model a simple spring mass system in 2D in COMSOL.
I would be very thankful for any advice and or direction that could help me carry out what I'm trying to model.
Best Regards
