High variation on results (induced voltage on a coil) - 3D Transient Flux

Hello.

I've been struggling with the simulation of a sensor consisting of a coil with a ferromagnetic core and a magnet. The main output to analyse is the voltage induced on the coil by a rotating target. I'm modeling the coil as stranded-coil conductor coupled with a series resistor (see attached circuit.png). When measuring the voltage across the coil, I'm looking at very high fluctuations in voltage (see attached results.png), if I take the derivative of the flux (flux.png) through the coil, the behavior is minimized a bit, but still present. 

Any ideas to improve this high variation?

 

Thanks.

    Hi,

    Can you send me you Flux project (zip format without results).

     

    Best regards.
