Abstract
A magnetic spring device with negative stiffness contains at least one first pole body combination composed of at least one first, at least one second and at least one third pole body, which each have opposite magnetic poles, with the pole bodies in the combination being aligned such that opposite poles are opposite one another and the first and the third pole bodies assume a defined distance from one another, in which the second pole body is arranged, with the pole bodies being arranged such that they can move relative to one another.
