Hello,
Im tyring to find the electric fields produced by the changing Bfield in my simluation. It is a very simple set up (see .mph file). I've tried using magnetic field and coil to produce the B-field but no Efield is shown on results. Not sure how to include the J=E formula into my simluation.

Have you considered using the mef physics instead?

Mr. Koslover,
The thought has crossed my mind. However, mef is a little more involved than mf when it comes to the physics. If you could provide a good mef example or detailed explanation that could really help. I'll do my best to describe the setup.
setup
1. 2D model
2. create a Bfield that oscillates at frequency 13MHz.
3. the field will tranverse a ring structure. The inside and outside of the ring will have different electrical properties. If possible the ring boundry will too.
4. Finally, plot the induced electric field in and around the ring. Along with the Bfield.
Any help is much appreciated. I was thinking if using mf and coil feature to generate the bfield in the frequency domain. I'll see if that works.

Hm, the induced electric field is available in mf. Check the available result quantities.
