modeling two magnets (one moving, one fixed)

Hell everyone!
I am trying to model two magnets (in 2D , i.e. 2 squares) - one is fixed and the other moves along the x-axis with some harmonic law (dx = sin(omega*t).
I defined the variable "t" [i used the generato -2D as a reference where they define t = 0 [sec] among their constants)
I am using the modules "magnetostatics" and "ALE" -
1) I realize that the "magnetostatics" doesn't solve transient problems, but I would like Comsol to solve the problem at each time step statically [i.e. move one of the magnets at the new location and recompute the solution]
2) When i compute the solution I don't even see the "boundary" of one the squares to have moved in time. I did change the conditions to predefined displacements, but nothing happens, so I am not sure what's actually happening.
Can any one perhaps enlighten me?
I am uploading my model, even though the last time I tried to run it , it gave me an error.
