modelling induced currents

Please login with a confirmed email address before reporting spam

Hello,

I am trying to find the induced current/voltage/power of a coil from the magnetic fields generated by another coil.

I am using the magnetic and electric fields interface, and I have defined my primary coil using a terminal and ground boundary condition on either end of the coil, under the magnetic insulation boundary condition.

I want to make the other coil passive and simply read out what gets induced in that coil, but I am not sure how. If I use another terminal, I need to set the voltage/power, but I don't want to excite this coil too, I just want to see what it feels from the other coil.

How could I go about doing this? Thanks.
