Magnetic Turntable
★Exhibit Content: Basic properties of magnets, non-contact force transmission ★Interaction: Mechanical interaction ★Operation: 1. Hold the knob of the operation panel and turn it clockwise or counterclockwise at a constant or variable speed. 2. Observe the transparent turntable set inside the glass cover; they will rotate synchronously under the action of magnetic force without any mechanical connection. Pay attention to the cartoon figures, bells, and other devices at the end of the turntable set, which will make corresponding movements or sounds as the turntables rotate. 3. Try changing the rotation speed and observe the changes in the response of the linked devices. ★Exhibit Description: The exhibit consists of three sets of manual magnetic turntables on the tabletop and a multi-stage linked turntable set inside a glass cover. By rotating the transparent turntable with embedded permanent magnets on the tabletop, visitors can drive the internal turntable set through the glass cover without any mechanical gears or belts. When the visitor turns the operation panel, the permanent magnets at the edge drive the adjacent turntables to rotate synchronously through the magnetic force of "like poles repel, opposite poles attract", thereby triggering the cartoon figures, bells, and other fun devices inside the glass cover to make corresponding movements, intuitively demonstrating the wonderful phenomenon of "non-contact energy transmission". ★Scientific Principle: Permanent magnets can generate magnetic force without direct contact. By utilizing the interaction force between magnetic poles to transmit power, non-contact power transmission is achieved. The power is transmitted sequentially to each stage of the turntables through magnetic force, continuously transmitting the manual mechanical energy to drive the end mechanism, intuitively presenting the physical law that magnetic force can transmit energy through space.
