Abstract: A system and device system for controlling a height of a levitated object based on a height selection made by a user. The system includes a user input device configured to receive the height selection made by the user, a base in communication with the user input device, and a power source. The base includes a magnet array having a central electromagnet configured to exert an adjustable magnetic force in a first direction, a plurality of peripheral electromagnets each being configured to exert an adjustable magnetic force in the first direction, and a permanent magnet being configured to exert a non-adjustable magnet force in a second direction at least substantially opposite the first direction. The power source is configured to deliver an adjustable current to the magnet array, such that adjustment of the current controls the levitation height of the object.
