Abstract
An apparatus for animating a magnetically levitated object. The apparatus includes a display with an overhead housing. A magnetic levitation and oscillation assembly is included with an electromagnet in the overhead housing. A levitated object with a body in which a magnetic element is embedded is positioned proximate to the electromagnet and levitated within the display. The levitation and oscillation assembly includes a levitation actuator driving the electromagnet with a control signal to generate a levitating magnetic field. The assembly includes an oscillating signal generator that oscillates the levitating magnetic field at an oscillating frequency. During magnetic field oscillation, the object body is levitated by the electromagnet and is concurrently subjected to first oscillating movements while attached elements such as wings are subjected to second oscillating movements near their resonant frequency with larger displacements, whereby the object body appears stationary while attached elements vibrate with a reciprocating or flapping motion.
