RE: [femm] Modelling Ferrite Cores

What kind of ferrite model did you use? One possible mistake can be that you
set the conductivity of the ferrite core. I would suggest to set it to 0
MS/m.

Hi

I am trying to model a small single winding inductor wound on a 
ferrite core. The operating frequency is 100kHz. So far the model 
does not give the expected answer and I can only assume that this is 
because my ferrite material model is incorrect. Has anyone found a 
way of successfully modelling ferrites. Do I have to do something 
with the laminations?

Thanks
