Claim:
1. A method of damping motion between a base structure and an attached component with a motion-damping system that extends within a gap that is defined between the base structure and the attached component, wherein the motion-damping system includes a magnetic assembly, a magnetically active body, and a tubular structure, wherein one of the magnetic assembly and the magnetically active body is located within the tubular structure, and further wherein the other of the magnetic assembly and the magnetically active body is operatively attached to a selected one of the base structure and the attached component, the method comprising: rotating the attached component relative to the base structure to rotate the magnetic assembly and the magnetically active body relative to one another, wherein the rotating includes permitting the tubular structure to rotate relative to the selected one of the base structure and the attached component, and further wherein the rotating includes deforming a viscoelastic material that is located within an internal volume of the tubular structure; and dissipating energy with the motion-damping system.
