Not able to properly use remesh feature in multiphysics stationary simulation

I have simulated a steel specimen that becomes deformed due to bending. For that, I use the solid mechanics interface in a stationary study. Parametrizing the magnitude of bending also works. Overall, it works as expected.
I have also simulated an electromagnet by using the magnetic fields interface and specifying a DC external current density in a stationary study. That also works well.
I have attempted to include both of them in the same model, where I want the specimen to be deformed, remeshed, and that new mesh be used in the magnetic fields stationary study. Oh, and I want to parametrize the magnitude of bending, such that the sequence of operations is:
1. Deform 1 mm relative to rest position (calculate from initial mesh)
3. Calculate DC magnetic fields (using remeshed geometry )
4. Deform 2 mm relative to rest position (calculate from initial mesh)
6. Calculate DC magnetic fields using remeshed geometry
and so on...
So far, I have managed to remesh by using ALE and the model works without errors. However, I have a hunch that the magnetic fields interface only takes into account the initial mesh. As a result, the magnetic field distribution remains the same, and the only reason why it follows the shape of the deformed specimen in the plot, is because I have added "Deformation" as an addition to the plot. Could this be the case, what do you think?
I have been struggling with this for quite a while. Any ideas/suggestions would be highly appreciated. Thanks in advance for your time,
