Biot- Savart simulation in Comsol

Please login with a confirmed email address before reporting spam

Hi Guys, I have some issue with Biot-Savart simulation in Comsol, actually, my physical setting is a two parallel rectangular coils represent helmholtz pair and other parallel coils represent maxwell pair, when I implement the excitation voltage to the lumped port of the model it created a non-uniform field.

So, my questions are, do you guys have an approximate model (i.e. using DC generated magnetic field as RF coil setting)? Second, do I need PML layer around the RF coil geomtery and if yes, I want to visualize inside the coils domain not outside it, so How I can set a PML like this.

P.S. I only have RF module, so no AC/DC module required?
