Two of these shaped Electromagnets, one on each end would handle the amperage required to torque the powerful fields:

store bought output coils would slip over axial tube magnets easy and neatly off to the sides. the magnets shift their field flux from this meg. almost too simple to do.

two stator arrays for the complete set and three off the shelf wire coils with core matching magnet size.
