Abstract:
A linear actuating device contains a top magnet and a bottom magnet. The bottom magnet is axially aligned with the top magnet. The top magnet and the bottom magnet have opposing magnetization. A washer is sandwiched between the top magnet and the bottom magnet. A top coil is positioned within the top magnet. A bottom coil is positioned within the bottom magnet. A slug is slidably positioned within the top coil and bottom coil. An actuating member is integral with the slug.
