Abstract: A magnetic device comprising at least one stator (1) and one translator (2), which translator (2) is movable along a translator movement path (3) in a translator movement direction (4) relative to the Stator (1),the translator (2) being coupled, at least in portions of the translator movement path (3), to an acceleration unit (5), which on coupling the translator (2) with the acceleration unit (5) generates an acceleration force state comprising at least a corrective force Fcorr acting on the translator (2), which acceleration force state can cause a movement of the translator (2) away from the stator (1), wherein when the translator (2) is coupled to the acceleration unit (5) and the translator (2) moves away from the stator (1), the sum total of the forces acting on the translator (2) in the translator movement direction (4) due to magnetism is greater than or equal to zero, so that the translator (2) can be separated from the attractive force generated by the stator (1) by means of the corrective force Fcorr.
