EM harvester with moving coil.

Hello,

I'am newby to COMSOL. i'm working on an EM harvester with a printed coil on a vibratng beam and a permanent magnet. I have some technical questions for the design.

1- is it possible to design a printed coil ? i was able to draw a 3D geometry with a liitle high as if it was printed and used numeric coil but it needs too much memory.

2- to use a permanent magnet i need all the structure to be housed in an air environement for boundaries condition. when i have a vibrating beam, is it possible to use a moving mesh or do i need to use fluid-structure-interaction module ? in this case must i keep the solid mechanics module or only fsi ?

Thanks
