Abstract
A rotation structure rotates a rotatable segment via the attraction between a number of electromagnetic elements disposed on another rotatable segment around a screw and a magnet disposed on another rotatable segment. The rotated angle of the rotatable segment can be controlled by selectably magnetizing the electromagnetic elements in response to an instruction generated by pressing a button formed on another rotatable segment.
