Material modeling is not just about programming. At present, there is still
no material model can predict high speed damaging/failure, let alone under
the 3 basic loading types, if added anisotropie and thermo-effect, and
hardening, it would be an impossiblemision for next decades. On the other
hand, no testing method/machine yet can obtain reliable data to validate
such theories, even to produce a reproduciable sample.

I think it should be:
Energy densty =-M*H
Force=-gradient E*V
where M=a*H, a is the permiability of the material, V is the
volume of the piece.
if the material or the field is not uniform, Force =
integral of (minus Gradiant E) by dV.
The problem is that the permiability changes by H and the
material's magnetization history and actually also the shape
of the piece(which decides the magnetostatic energy of the
piece), whether the iron has cristalline anisotropy and

google for mean curvature flow, it can be done without parameterization.
you can also look for modified version of it, which can keep features better,
especially since your shape is tube-like, it means the two principal
curvatures
are quite different (one being almost 0), so you have to take the
anisotropy into account. there are quite some papers on this.
