【Core Demonstration Function】：This product vividly demonstrates the mechanical motion of objects driven by cathode rays, directly proving that cathode rays possess measurable momentum and energy, making it an ideal tool for physics education and scientific demonstrations. 【Precision Structural Composition】：Crafted with a glass blister, guide rail bracket, small wing wheel, wafer electrode, and sturdy bakelite seat, its modular design ensures stable performance and clear observation of the cathode ray impact effect. 【Intuitive Visual & Kinematic Effect】：The wafer electrode emits cathode rays that strike the fluorescent-coated wing wheel, causing the irradiated side to glow while propelling the wheel to scroll along the direction of the cathode rays, creating a visible, easy-to-understand demonstration of particle momentum transfer. 【Adjustable Direction Experiment】：By rotating the induction switch, you can reverse the direction of cathode ray emission (both wafer electrodes are capable of emitting rays), which in turn reverses the wing wheel’s movement, enabling interactive exploration of cathode ray properties. 【Fundamental Physics Insight】：This experiment clearly illustrates that cathode rays are streams of particles capable of transferring momentum and energy to irradiated objects, serving as a foundational teaching aid for atomic physics and electromagnetism education.
