Can I investigate magnetic flux phase?

After poking around the software I wanted to ask a quick question:
Is there a way I can look at the phase of an alternating magnetic flux? I am thinking about induction motors and shaded poles so I'd like to model a typical single-coil inductor where a phase shift is implemented in the magnetic flux across the air gap. Any quick pointers would be very appreciated!

Peter, Sure you can. The magnetic flux density components are complex quantities.

Ok, based on your comment I'm seeing that I need to activate the "Split complex variables in real and imaginary parts" check box in the "Compile Equations: Stationary" and then plot expressions like real(mf.normB) and imag(mf.normB) to access the complex values, etc. to get explicit phase information. Can you confirm this is the correct approach?
CORRECTION: I suppose I'll want to plot real(mf.Bx) imag(mf.Bx) etc.
Thank you for your advice.

You don't need to split the complex variables. The real() and imag() operator extracts the components.

Oh ok. Thanks! Applying this to an application model now and getting somewhere...
I appreciate it.
