Power-Generation Contest
★Exhibit Content: Electromagnetic Induction ★Interaction: Electromechanical Interaction ★Operation: 1. Exercise on the stepper, bicycle, and treadmill respectively; 2. Observe the brightness changes of the LED lighting column in front and experience the power generation effects of different exercise modes. ★Exhibit Description: "Power Generation Competition" is an interactive exhibit for physics and energy science popularization, designed specifically for the energy science exhibition area, and is also a recommended exhibit of PopsciCat Exhibit Store. The exhibit consists of a stepper, a bicycle, and a treadmill, demonstrating knowledge related to the piezoelectric effect and electromagnetic induction principles. When visitors perform exercises such as stepping, pedaling, and running on the exhibit, the LED lighting column in front lights up. The faster the movement, the greater the power generation, and the higher the brightness of the lighting column. Visitors can intuitively compare the power generation efficiency of different exercise modes and experience the process of converting mechanical energy into electrical energy. ★Scientific Principle: A DC generator is a device that converts mechanical energy into DC electrical energy, utilizing the principle of electromagnetic induction. The coil is connected to the brushes through two semicircular slip rings, and then through wires and a light bulb to form a closed circuit; when the coil rotates, it cuts the magnetic lines of force, thereby generating an induced electromotive force in the circuit, and the lighting column lights up. The faster the person moves, the faster the coil rotates, the more times the conductive coil cuts the magnetic lines of force per unit time, the more electrical energy is generated, and the brighter the lighting column becomes. The piezoelectric effect and electromagnetic induction principles are widely used, such as in transducers, piezoelectric actuators, and piezoelectric sensors that utilize the piezoelectric effect, and AC generators, induction motors, and transformers that utilize the electromagnetic induction principle.

★Exhibit Content: Mechanical and Electrical Energy Conversion, Energy Conservation Science Competition Experience ★Interaction: Electromechanical Interaction ★Operation: Ride the fitness bicycle; pedal hard to drive the device for power generation; observe the number and brightness of LED lights on the spherical model; multiple people can participate simultaneously in a power generation competition. ★Exhibit Description: The exhibit consists of 3 fitness power generation bicycles, a spherical luminous main body, equipment base, signal transmission lines, and a 5mm thick acrylic UV spray-painted instruction sign, and is a recommended exhibit of PopsciCat Exhibit Store. Three visitors can simultaneously ride the fitness bicycles for interactive competition. The mechanical energy output from pedaling is transmitted to the power generation unit through the transmission mechanism, and the power output is fed back in real-time to the central spherical device. The faster the pedaling, the greater the electrical energy output, and the more LED lights on the sphere surface light up and the higher the brightness. By competing for the lighting effect, visitors intuitively experience the complete process of human power generation, concretely understand abstract energy conversion knowledge in a game competition format, and enhance their awareness of the law of energy conservation. ★Scientific Principle: This exhibit demonstrates the law of conservation of energy: energy cannot be created or destroyed, only converted from one form to another. Visitors pedal the bicycle to output human mechanical energy, which drives the generator rotor to rotate at high speed through the transmission structure, converting mechanical energy into electrical energy using the electromagnetic induction principle. The electrical energy supplies the LED lighting module on the spherical body to emit light, achieving the conversion of mechanical energy into light energy. The entire process fully presents the transfer and transformation of energy.
