ABSTRACT:
A core made of a soft magnetic material is supported to be movable, and a permanent magnet is mounted to move with the core. At least one electrically conductive drive coil is located adjacent the core and one pole of the permanent magnet. A casing, made of a soft magnetic material, is located adjacent to the drive. An electrically conductive sense coil is located adjacent one end of the core, such that when electrical current is passed through the drive coil in a first direction, the core is moved in a first direction and an electrical property associated with the sense coil is altered, thereby indicating the position of the core, and when electrical current is passed through the drive coil in a second direction, the core is moved in a second direction and an electrical property associated with the sense coil is altered, thereby indicating the position of the core.
