Adding a constant, homogeneous magnetic field in the MEF physics model

I am trying to model the magnetic field produced by a wire with a particular geometry which carries a certain current. I have managed to do this so far by using the Magnetic and Electric Fields interface, where the geometry was imported from a 3D CAD file, and then defined a "Terminal" and a "Ground" connection using the "Magnetic Insulation" options. I then define a large cube with material "Air" to contain the wire structure and evaluate the magnetic field within.
My problem is that I now wish to add to this field produced by the wire a constant, homogeneous magnetic field. I would like to have a field with three components (but not necessarily the same value for each, the same as would be produced by 3 pairs of Helmholtz coils).
I think that I need to set a boundary condition at the faces of my "air cube", but cannot work out exactly how to do it.
If anybody has any suggestions, it would be greatly appreciated!
