Spinning Silver Egg

Science Caravan · Electromagnetism

Dimensions: Transport dimensions: 540×440×640mm, Display dimensions: 540×440×1450mm. Composition: Consists of an ABS plastic molded cabinet, ABS plastic molded pedestal, ABS milky white plastic molded operation countertop with color silk-screened flip-up instruction panel, transparent disc and acrylic cover, silver egg, three magnets placed at 120-degree angles to each other, transmission mechanism, etc. Scientific Principle: On the disc below the silver egg are three permanent magnets at 120° to each other. Turning the handwheel rotates the disc, and the three rotating permanent magnets generate a rotating magnetic field in space. The silver egg is a closed conductor, and the rotating magnetic field induces a current in it, forming another magnetic field. Because the silver egg's mass is unevenly distributed, under the interaction of the two magnetic fields, the silver egg begins to rotate, and then, under the action of centrifugal force, gravity, and friction, it stands upright. Operation: Press the button and observe the changes in the silver egg.
