Abstract
The invention relates to a popular amusement device with a personal transportation device, moving along a guide track arrangement (14), and eddy-current braking device (10, 70), comprising a magnet arrangement (10) and an induction body (70), for the selective braking of the personal transportation device, with one of the pieces of either the magnet arrangement (10) or the induction body (70) being provided on a guide track arrangement (14) and the other piece (10 or 70) being connected to the personal transportation device. The magnet arrangement (10) comprises at least two partial magnet arrangements (18, 20) each with at least one permanent magnet (74, 76, 78, 82, 84, 86), said partial magnet arrangements (18, 20) are, at least in the operating position thereof, arranged essentially orthogonal to the braking area guide track direction (B), at a separation (a) from each other, with the induction body (70) being arranged between the partial magnet arrangements (18, 20) during the braking. According to the invention, the partial magnet arrangements (18, 20) may be displaced relative to each other.
