MHD Module not effecting flow

  Hello all,
  
  I saw a couple of posts which asked the same question I have, but none of them had an actual solution to the problem.
  
  I am currently running a compressible flow case with the MHD Module. I am running on the Realizable k-e viscous solver, with ideal gas densities for the fluid (air). I have increased the mangetic permiability and electrical conductivity of the fluid for the purposes of troubleshooting.
  
  The MHD Module generates the external magnetic field, calculates/displays the induced magnetic fields, and calculates/plots the lorentz force generated by the field. Despite all of this, the flow itself seems to be completely unaffected.
  
  If you need any pictures, please let me know.

  For reference, the flow is a Mach 7 (2401 m/s) flow and I am seeing a lorentz force on the order of 1000 N/m^3. I originally thought the issue could be that the lorentz force isn't powerful enough, but this seems like a reasonable force magnitude, no?
