ACDC Time harmonic analysis: The varying and the constant

I'm using the ACDC module to simulate a time-varying current in a conductor under the effect of a permanent magnet (Time-harmonic analysis).
While I define the magnet's subdomain using Magnetization (B=uH+M), I have noticed that this value -which should be independent of time- varies when I alter the phase(solution at angle). I basically have a time-harmonic current which I want to subject to a steady magnetic field, but it seems that the ACDC module is making all parameters 'beat' at the given frequency.
How can I fix the magnetization of a subdomain while maintaining time-harmonic variation in another? The other subdomain is excited using a Voltage. I have thought of dividing the magnetization value by (exp(j*phase), but is this sound?
Any thoughts would be greatly appreciated.
