Magnetic Field due to time varying Electric Potential

Please login with a confirmed email address before reporting spam

Hello Everyone,

I am relatively new to COMSOL, I am trying to build a model to compute the magnetic field generated due to time varying electric potential along one of the boundaries. I believe the model is correct but I don't know why it doesn't compute the magnetic field; can anyone help me please??


The model is a multiphysics model which includes electrostaic module and electromagnetic module.

Hi

the RF module needs a current to derive a potential A, not just an electric field on a boundary

Good luck

Dear Ivar,

Thank you very much for your immediate response,

Isn't there any other way to solve for the magnetic field generated due to time varying electric field without introducing a current??

Hi

if its a periodic "time variant" case use the "emw" with a frequency domain sweep, then you could probably use ES to define your E field

So I can use structural mechanics to move a magnet ina coil so current is produced ??
