To enhance students’ understanding of energy conversion principles in physics and electromagnetic coil cannon fundamentals, this study designs and develops an experimental demonstration device. Core components include a DC power supply, charger, pulse energy storage capacitors, five-stage drive coils (wound with 1mm-diameter copper enameled wire, 40 mm long, 6 layers, evenly spaced on the launch tube), projectiles, and photoelectric switches. When demonstrating, the DC power supply charges the capacitors via the charger. The first coil is manually triggered, while the latter four use photoelectric sensors (with light-transmitting plexiglass launch tubes) to trigger thyristors, realizing sequential capacitor discharge to accelerate the projectile until it exits the tube. Residual capacitor voltage is manually discharged post-experiment for safety. This device is easy to use, simple to fabricate, and engaging. It intuitively shows projectile acceleration via drive coils, deepens students’ grasp of electric-magnetic-mechanical energy conversion, improves their theory-practice ability, and boosts interest in physics learning and scientific exploration.

摘要

To enhance students’ understanding of energy conversion principles in physics and electromagnetic coil cannon fundamentals, this study designs and develops an experimental demonstration device. Core components include a DC power supply, charger, pulse energy storage capacitors, five-stage drive coils (wound with 1mm-diameter copper enameled wire, 40 mm long, 6 layers, evenly spaced on the launch tube), projectiles, and photoelectric switches. When demonstrating, the DC power supply charges the capacitors via the charger. The first coil is manually triggered, while the latter four use photoelectric sensors (with light-transmitting plexiglass launch tubes) to trigger thyristors, realizing sequential capacitor discharge to accelerate the projectile until it exits the tube. Residual capacitor voltage is manually discharged post-experiment for safety. This device is easy to use, simple to fabricate, and engaging. It intuitively shows projectile acceleration via drive coils, deepens students’ grasp of electric-magnetic-mechanical energy conversion, improves their theory-practice ability, and boosts interest in physics learning and scientific exploration.
