Rotating Magnet question - do physical properties also have to be "rotated" ?

I have a problem about rotating physical quantities together with the domain the occupy.
Here is my problem:
When I impose a rotation on a magnet and I impose a certain magnetization vector , do I have to impose the same rotation function for the magnetization vector as well?
Right now i have a spinning magnet about a fixed axis (I used the ALE module), and I impose M = (M_bar, 0) in the subdomain description under one of the AC/DC modules.
At other time steps I still see the same M = (Mbar, 0) , that is M_y = 0 for all time instants I solved for.
Now, if I plot the magnetization M_x , the rotated square shows up and the value for M is Mbar inside the square and zero outside. That seems right.
When I plot let's say the magnetic potential, my solution doesn't change in space even though I see the square rotating. It's like the magnetic potential was solved for the value M= (M_bar, 0)
The magnetization should "occupy" the region of the square and it does, and the potential should look different (i.e. rotated), but it does not.
Any thought?
