Hello,

I am a preparatory student, for my project (tipe) which concerns induction charging, I would like to carry out different modeling with comsol. But by looking a little I did not find any help or model made beforehand. Can you give me the various aids to carry out the future modeling? I found this on the internet but not in the comsol database (see attachment). My goal would be to: - model the magnetic field between two coils one above the other (a few centimeters apart). - model the fields between three coils, two side by side spaced a few centimeters apart and the last one above (in the middle) the two previous ones. thank you for your response Lucas

Lucas,

there is an example for Helmholtz coils in the application library that comes with COMSOL.

Cheers, Edgar

Hello,

thank you very much for your answer. It's possible to optain the file with the coils already modeled and then do the desired experiments?

Cheers, Lucas

The coils are in the model. You only need to modify them according to your needs.

If you have COMSOL, go to Files->Application Libraries, and search 'Helmholtz Coil'.

That model is part of the AC/DC Module's application libraries, so you will need both COMSOL Multiphysics and that module on your license.

The model and its documentation can also be found in the Application Gallery on COMSOL's website: here is the link.
