ABSTRACT:
A new design of picture frame that levitates and rotates in the air without mechanical support is described. A permanent magnet (5) is mounted on the top of the picture frame (2) such that the center of the magnet coincides with a vertical axis through the center of gravity of the picture frame. The picture frame is positioned below and within an outer fixed framework (1). An electro-magnet (3) is mounted on the top of the fixed framework such that the center of the electro-magnet (3) coincides with the said vertical axis. An additional set of electro-magnet on the fixed framework (8, 10) and permanent magnet on the picture frame (6, 10) are employed for nearly periodic rotation of the picture frame.
