Railgun

The driving force of a railgun power is the magnetic field created when electricity runs through the rails from the positive to negative ends. The more electricity running through the rail, the stronger the magnetic field. The railgun projectile is positively charged so it is repulsed by the positive end. In most railguns millions of amperes are ran through the positive end to the negative end. When the positive charge run through the railgun nears and leaves the projectile lorentz force acts on the projectile. This propels it out of the rail gun.
