ABSTRACT:
A system and method for moving an object is disclosed. In one aspect, there is a device for moving an object. The device comprises a penetrating structure comprising an externally threaded surface. The device further comprises a receiving structure comprising an internally threaded cylinder surrounding the penetrating structure. The device further comprises a source of magnetic flux configured to magnetize the externally threaded surface with a first polarity and to magnetize the internally threaded cylinder with a second polarity that is different from the first polarity. The device further comprises a conductor positioned between the penetrating structure and the receiving structure configured to conduct an electric current. The device further comprises a sensor configured to determine the radial position of the penetrating structure with respect to the receiving structure. The device further comprises a controller configured to control the electric current in the conductor based on the determined radial position.
