Hello,
I am trying to simulate the magnetic field of a flat spiral coil and calculate it's inductance, I've built a 3D model using parameteric equation and sweep, When using the stationary study the inductance value is close to the measuerd one (simulated: 8uH, measuerd: 7.3uH) However, when using the frequency domain the calculated inductance is -9.8!!! is there any explination for that?
Also, the simulated and measuerd values of magnetic field are slightly different especially -and more significantly - at small distance from the coil (attached figure) .. what is the expected discrepency between the measuered and simulated fields?
Thanks,

There are at least several possibilities. I encourage you to post your model to the forum so that others can examine it and identify any problems or mistakes in it. You might also want to describe your physical experiment in some detail too, since sometimes experimental measurements can have sources of error as well.
