摘要：
An apparatus includes a plurality of beads and a plurality of links joining the beads together. Each bead includes a housing, a passageway extending through the housing, and at least one annular magnet. The passageway defines an axis. The at least one annular magnet is coaxially positioned about the passageway. The housing defines a gap adjacent to the at least one annular magnet. The gap is sized and configured to allow at least one annular magnet to rotate relative to the housing about a rotation axis. The rotation axis is offset from the axis of the passageway. Portions of the links are slidably disposed in corresponding passageways of the beads.
