Abstract:
1. An apparatus for animating a doll using electromagnets is characterized by: a container filled with liquid in a hermetically sealed inner space, and including a bottom-opened transparent cover of a predetermined form, a floor plate adhered to the opened portion of the cover that hermetically seals an inner space of the cover, and a support case disposed with an inner space that accommodates and wraps a part of the cover and the floor plate and that supports the cover and the floor plate; a doll disposed inside the cover of the container, wherein the doll has a shape of a human being and includes permanent magnets vertically installed in the head and both feet, and auxiliary magnets installed at both elbows and both hands, each being connected to the permanent magnet of opposite foot via an electric wire; a plurality of electromagnets arranged along a ring-shaped core disposed at a lower surface of the floor plate of the container, where polarity of each electromagnet is independently determined by a control current; a plurality of variable magnetic poles, each protruded and extended from the core between neighboring electromagnets and each one or more variable magnetic poles arranged at a lower surface of the floor plate and an external surface of the cover; a controller applying different control currents to the plurality of electromagnets to allow each of the variable magnetic poles to have a different magnetic force at different times, whereby attractive forces and repulsive forces are provided to the permanent magnets and the auxiliary magnets of the doll; and an electric power supplier supplying electric power to the controller.
