How to make a uniform magnetic flux density

Hi all, I'm trying to model a magneto-mechanical interaction (my focus is on the structure) and I need to apply a uniform magnetic flux density in a cube of air (which is my domain) in the z direction. Is there a way to do it? I've tried different things (magnetic potential, magnetic field and others) but they don't work. Thank you for your help

A simple approach using magnetic potentials worked for me. Much like a simple capacitor in electrostatics. See attached. I'm assuming you have version 6.3.

Out of curiosity: Why do you need to compute the magnetic field at all? Why not simply use its known value in the structural equations? It would save you (and your computer) some work (and memory, and time).
