A magnetic spring includes magnetic elements placed coaxially and installed with possibility of translational relative displacement and interaction, as coaxial rings in cross section, those form a magnetic circuit, and the outer magnetic element that partially or completely surrounds the inner magnetic element. The outer magnetic element is in form of a tube that partially or completely surrounds the inner magnetic element at its working motion, with the length of the inner element larger or smaller than the length of the outer element, the outer and the inner elements are permanent magnets, at that the inner magnetic element is made of magnetic-hard or magnetic-soft material as a solid of revolution and has anti-parallel magnetization along the direction of its motion with respect to the outer magnetic element. |
