Hi,
I'm Gioia and I'm a beginner of Comsol. I'm trying to evaluate the attraction force between two cylndrical magnets.
In my simulation I called:
-the force that the big magnet exerts on the little magnet: F3
-the force that the little magnet exerts on the big magnet F5

To be realistic, the two forces have to be similar, but in the simulation that I have done, F3 and F5 are very differents.

I attached the simulation. Could anyone tell me where is the mistake?

Thanks in advance for your help,

Gioia :)
