Impedance plane for eddy current probes

Hi,

I modeled an eddy current probe AC/DC module, axial symmetry 2D, Quasi-static, time-harmonic analysis. I checked my model using a gaussmeter in a real probe and the answer of COMSOL was very close to the measurements in the gaussmeter, but now I'm trying to make the impedance plane of my probe. Does anyone know how can I do that using COMSOL? I mean, there is a way I can extract the inductive reactance (XL) and the resistance (R) of COMSOL. I'm attaching my model.

Thanks,

Cesar

Hello !

Did you manage to do so ?

Because, i'm actually trying to modelize a helmholtz coil, with a steel bar inside (with a crack on it), and I want to see the effects of the presence of the bar's crack on the impedance plane.

So I wanted to know if you managed to have R and X, and if you could help me if yes ?

Thanks in advance.

Sorry Ernest, but I didn't have success on my impedance plane.
