Abstract

A magnetic linear drive has a coil in whose interior the current can produce a magnetic flux in an axial directions, having an armature which can move only at right angles to the axial direction and which has a magnetically active part which is magnetized, in particular, parallel to, but in the opposite direction to, the axial direction. The armature is driven by a current surge which accelerates the magnetically active part toward the coil center irrespective of its initial position.
