The electromagnetic gun is a kind of advanced kinetic energy made by electromagnetic launch technology. Unlike traditional cannons, which use gunpowder gas pressure to act on projectiles, electromagnetic guns use the ampere force generated by the electromagnetic field in the electromagnetic system to accelerate metal projectiles to reach the kinetic energy required to hit the target. Unlike traditional gunpowder-propelled cannons, electromagnetic cannons significantly increase the speed and range of projectiles. The power of this kit is relatively small and suitable for experiments. Although it is relatively safe, do not aim the barrel at weak parts such as the eyes when shooting. Under 14 years old, please use under adult supervision!
Features of this kit:
1. The circuit is simple, reliable, and practical;
2. This kit is equipped with an acrylic plastic case, which is beautiful and effectively protects the circuit components, which is convenient for demonstration.
More importantly, the electromagnetic gun is a device that works under high voltage, and the voltage in its energy storage capacitor can reach 100V. Although the energy is small and will not cause fatal damage to the human body, it can still cause electric shock accidents. The safety is greatly improved when the entire device is placed in an insulating plastic case.

Usage instructions:
1 Turn on the power switch (button switch K1); at this time, the green light-emitting diode lights up, and the circuit starts to charge the energy storage capacitor. Wait for about 2-3 minutes, and the red light-emitting diode is also on. At this time, the energy storage capacitor is fully charged, and the launch is ready;
2. Insert the projectile (cylindrical carbon steel rod) from the rear of the barrel, and its tail should be flush with the tail of the barrel (you can try to change different positions by yourself, 1mm each time, and fire when you find how close it is to the edge of the coil furthest away). Press the launch button (button switch K2), the projectile will fly out of the gun barrel, and the launch process is completed. Note that the action of pressing the launch button should be crisp, and release it as soon as possible after pressing.
Precautions:
1. The internal working voltage of this device can reach 90~100V, which exceeds the international safety voltage standard of 36V. Therefore, when it is powered on and working, do not touch the internal electronic components; otherwise, electric shock accidents will occur. The insulation of external electronic components such as coils is relatively thin, so avoiding damage and leakage caused by rubbing is necessary. The switch is also a weak link. If it is exposed, the risk will be higher in the version without a casing, so pay attention to handling. Self-assembled circuit boards inevitably have errors or faults. If the boost circuit part is already working normally, the voltage of the energy storage capacitor (1000uF/100V) may have been charged to a higher value, causing electric shock hazards. Therefore, before troubleshooting and processing, first use a multimeter to measure the voltage at the two legs of the energy storage capacitor, or directly use a plastic-skinned wire (both ends are stripped to expose the copper wire), pinch the plastic skin and use both ends of the copper wire Touch the two feet of the capacitor to discharge. After the charge is completely released, the capacitor voltage will drop to 0V, and then it can be safely operated with bare hands.
