AC/DC and moving mesh for linear motion

I am working on the problem that involves linear relative motion between objects. In particular I am interested to move a permanent magnet above some conducting bar in order to calculate the resulting induced eddy currents distribution. The speed of the magnet in general can be arbitrary and change in time.
I have made a simple 2D “try” model coupling the ALE moving mesh and quasi-static magnetic module but I get problems with inverted mesh elements, even for constant velocities. You can find it attached to this post.
I am not an advanced user of ALE moving mesh module, so I am not sure if I could use it for problems involving linear relative motion.
I have tried the rotational motion (2D generator example) wit identity pairs. It is working fine for this kind of applications.
The final goal is a 3D transient simulation, so I am searching for some elegant solution excluding remeshing if possible.

I'm dealing with the exact same problem without any success. did you solve your problem? if so what did you do, I would appreciate if you can help me find out how should I set up the model, by the way I'm working with comsol 3.5 and the file that you've attached is created with version 3.5a so I could'nt open it.
thanks in advance
