Looks OK to me. The magnitude of the magnetic field in Paraview appears to be always a postive number, but the components x, y, z oscillate. I used your sif, but I had to build the mesh.

Have you considered p elements as an alternative to higher order node elements.

Your flow appears to be very turbulent which can be a challenge in Elmer.

I may have mixed up the coil and the core in my sif, need to verify the bodies.
Also use the elemental results, the ones ending in e.

try
ElmerGrid 2 2 deuteron_chamber -partdual -metiskway 16

All of these threw an error trying to read that files

NETGEN error

They are boundary elements so if you do not target those boundaries in the sif file and impose boundary conditions on them they will be ignored by the solver. Same with bodies, if you do not create the body in the sif, a body in the mesh will be ignored.

This project couples magnetic force to displacement, although the magnetic field is not electrical induced
but you should be able to go from electrical field to magnetic field to mechanical force

After the refining by splitting, I recombined the triangles to quads, went 2nd order, and the all of the errors went away and a solution was obtained.
