Assigning material (iron, air or...) to the permanent magnet domains in Magnetic Fields (mf) study.

I am modeling a generator in which I have used relative velocity of permanent magnets and coils to generate emf.
I have successfully applied magnet properties (magnetization) in the study using a "amper law" . However, to make the system run, I need also to assign a material such as air or iron to magnet domains, otherwise it gives me errors!
Why is that and what material should I use for that?
I have seen in the library model of permanent magnet that in "Magnetic Fields, No Currents(mfnc)" study, no material (air , iron or ...) is assigned to the permanent magnet domains. why in this case the system run the model with no error?
