Hello,
I'm new to Comsol and i'm trying to create a multi-turn coil with a metal rode inside it, for induction heating process.
When I compute the magnetic field around the coil, some line go trough the coil itself. So I wanted to ask you guys if it's normal and if someone can check if my simulation is correct.
I wondered too if it's correct to Frequency Domaine study to give an AC current trough the coil. I saw that there's an Harmonic Perturbation parameter in the coil.
Thank you for your time
