Magnetic & Mechanical force coupling

Hello, I'm running a Magnetic Fields (mf) and Solid Mechanics (solid) simulation, on an iron ring with a coil winding around it in order to see the deformation field and stresses due to the magnetic forces acting on the solid body. Although the magnetic field solution looks ok, the deformation field is absolutely 0. I checked with probes and the maxwell stress on the body isn't 0. I also activated the Lorentz Coupling from the Multiphysics tab although the lorentz forces should be zero but still no deformation field. Do you have any advice how to couple the maxwell stress field and the mechanical stress field?
Thanks in advance! Yonatan Petcho
