mini Railgun

This is a desktop electromagnetic railgun designed for scientific education and physical experiments. The projectile is a 10mm aluminum nail, which can be readily purchased. It requires two M3x28mm screws for fixation.

Regarding the capacitor, the voltage only needs to be within the range of 450V to 900V, but when the voltage is close to 900V, the stored energy should not exceed 200J to maintain efficiency, as exceeding this range would reduce efficiency.

However, at 450V, the stored energy should not exceed 300J. The coil turns for the upper and lower layers should not be less than two turns, and can be adjusted according to the amount of stored energy.

As long as it operates within the above range, the railgun can be fired.

• Projectile: 10mm aluminum nail, easily obtainable.
• Voltage range: Can use anywhere from 450V to 900V.
  • When the voltage is close to 900V, the stored energy should not exceed 200J, or efficiency will decrease.
  • When the voltage is around 450V, the stored energy should not exceed 300J.
• Coil turns: The upper and lower layers should have no fewer than two turns, which can be adjusted based on the stored energy.
• Firing conditions: The railgun can be fired as long as it operates within the above parameters.
