small update. someone showed me a cool programm called vizimag. it shows field lines and i adjusted my design to it.

how are you planning to drive it?
I don't see any coils or hall effect sensors.

Why need for MU metal? From the descriptions in here this type of metal doesn't seem so special at all. If you put a steel plate with certain width on a magnet pole most of the magnetic strength is absorbed as well, and they are much easier to get. You can try it out yourself by putting a thin iron plate in between 2 magnets (same poles facing the plate). Both magnets will clung to the plate, they're just not attracted that strongly.

the pole faces dont approach each other in my new design. i should change the description on my picture... BUT I CANT! no modify button...
