A magnetic device is disclosed for entertainment, education or magnetic therapy. The device includes a transparent annular tube having magnetic elements that slide within the tube cavity. The magnetic elements are arranged within the tube whereby the same poles on the magnetic elements create repulsive forces between them as the elements slide within the tube cavity, and contact between each magnetic element is prevented and the magnetic elements remain spatially separated within the tube. The magnetic device includes a wearable structure holding the tube with the magnetic elements.
