Invention on Instagram: "An electromagnetic coil accelerator, uses magnetic fields to propel objects at high speeds without the need for chemical propellants. The system works by running electric current through a series of coils which generate pulses of magnetism. As the projectile moves forward, each coil activates in sequence, pulling it further down the barrel until it exits at remarkable velocity. The underlying principle is simple, but the engineering required to synchronize the magnetic p
