Electromagnetic Induction Tomography simple model

Hi,

I am trying to make a very simple 2D model where I have 2 coils in which in between is a medium (air). One of these coils will be excited and have a magnetic field in the direction of the second coil. I would like to measure the voltage induced in this second coil.

I am having trouble with creating a 2D coil sensor. I'm not sure how to create the coil.

Thanks,
