Abstract
The system contains a top permanent magnet and a bottom permanent magnet. The bottom magnet is axially aligned with the top magnet. The top magnet and the bottom magnet have substantially opposing magnetization. A top coil is positioned substantially enclosing the top magnet. A bottom coil is positioned substantially enclosing the bottom magnet. A ferromagnetic spacer is positioned between the top magnet and the bottom magnet. A slug is slidably positioned within the top coil and bottom coil. The slug has an opening formed therein. The slug opening is sized and positioned to slidably receive at least one of the top magnet, the bottom magnet, and the ferromagnetic spacer. An actuating member is integral with the slug.
