s use two parallel metal rails connected to a power supply. When a conductive projectile is placed between the rails, the circuit is completed and a magnetic field is created down the rails up to the point of the projectile. This creates a force which pushes the projectile along the track, accelerating it to great speeds until it leaves the rails and the circuit is broken.

Coilgun A coilgun, also known as a Gauss rifle, is a type of mass driver consisting of one or more coils used as electromagnets in the configuration of a linear motor that accelerate a ferromagnetic or conducting projectile to high velocity. In almos ...

s, on the other hand, have a barrel made up of coils of magnetic material. The projectile is placed between the coils, which have a pulse of electricity passed through them. This pulls the projectile into the centre of the coil. The coils further down the track are then pulsed in sequence at specific times, accelerating the projectile until it leaves the barrel.
