An electromagnetic railgun is a cutting-edge technological concept that uses electromagnetic force (Lorentz force) instead of traditional chemical energy to accelerate projectiles. Its core principle lies in the instantaneous generation of a strong magnetic field within a coil surrounding the launch tube when a strong current passes through it instantaneously. This induces eddy currents within the conductive metal projectile (such as a small ball) in the magnetic field, resulting in a powerful thrust perpendicular to the magnetic field, propelling it at high speed along the launch tube. This purely electric acceleration method theoretically can achieve initial velocities and ranges far exceeding those of traditional artillery, making it a crucial research direction in modern military technology and future aerospace launches. Our interactive "Electromagnetic Railgun" exhibit condenses this complex physics into a hands-on, immersive experience. Within a 3100*3100*3000mm square space, pa
