Abstract
A yo-yo having improved spin time is disclosed. The yo-yo has a body comprising two side members joined together at their centers by a fixed axle. A yoke for receiving a string in winding relation is magnetically supported for substantially frictionless rotation about the axle. A pair of radially-magnetized ring magnets disposed at opposite ends of the yoke are received within a corresponding pair of radially-magnetized ring magnets disposed within recesses in the side members. A pair of axially-magnetized ring magnets disposed at opposite ends of the yoke confront a corresponding pair of axially-disposed ring magnets set into the body side members. The magnets are magnetically polarized such that they mutually repel each other. As a result, the yo-yo is free to spin around the yoke for an extended period of time.
