Abstract
The invention relates to a linear magnetic drive consisting of an iron core and a coil. A yoke and a constant magnet are connected to a movable armature. When the armature is placed in a first terminal position, it is supported by magnetic forces produced by the constant magnet and the yoke which is used as a bridge in the iron bore.
