摘要：
A magnetic spring utilizing spatially modulated magnetic field patterns of magnetic regions for both stator and slider, allowing custom force curves over the range of motion. Also disclosed is a magnetic spring whose slider can be rotated relative to the stator on the axis, such that the alignment of the spatially modulated magnetic field patterns of the slider and the stator is altered, resulting in changeable force curve for the spring, selected by rotating the slider.
