Levitation device with horizontal spin axis

摘要

A levitation device including an object levitatable at a predetermined position, wherein the object comprises a spinning magnet, the spinning magnet having a substantially horizontal spin axis defining an axial direction and the spinning magnet having a magnetization direction parallel to the spin axis, the device further comprising: a pusher magnet arrangement configured to produce a magnetic field at the predetermined position that is in the opposite direction to the magnetization direction of said spinning magnet; a lifter magnet arrangement lower than and to either side of the predetermined position, having a magnetization direction parallel to the magnetization direction of the spinning magnet, and having a recess under the predetermined position; and a puller magnet arrangement above said predetermined position and having a magnetization direction antiparallel to the magnetization direction of the spinning magnet.
