The Gauss gun (often called a Gauss rifle or Gauss cannon) is a device that uses permanent magnets and the physics of the Newton's cradle to accelerate a projectile. Gauss guns are distinct from and predate coil guns, although many works of science fiction (and occasionally educators [1]) have confused the two.
Simplified diagram of a multistage coilgun with three coils, a barrel, and a ferromagnetic projectile. A coilgun 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.

Although the "GR" designation purports the device to be a "Gauss Rifle", as evidenced both by the company [1] and media reports, [2] [3] this is technically a misnomer on two counts—it is neither a rifle (as it doesn't use rifling) nor a Gauss gun (a type of accelerator that uses permanent magnets and is distinct from a coilgun).
The Gauss GP-219 looks like it came straight from level 5 of Duke Nukem 3D, and rocks a PIC microcontroller, dual coils with "precision pulsing" to fire steel projectiles, twin infrared sensors to ...
A magnetic weapon is one that uses magnetic fields to accelerate or stop projectiles, or to focus charged particle beams. There are many hypothesized magnetic weapons, such as the railgun and coilgun which accelerate a magnetic (in the case of railguns; non-magnetic) mass to a high velocity, or ion cannons and plasma cannons which focus and direct charged particles using magnetic fields.
A railgun or rail gun, sometimes referred to as a rail cannon, is a linear motor device, typically designed as a weapon, that uses electromagnetic force to launch high-velocity projectiles. The projectile normally does not contain explosives, instead relying on the projectile's high kinetic energy to inflict damage. [ 2 ]
For a space gun with a gun barrel of length (), and the needed velocity (), the acceleration is provided by the following formula: [citation needed] = For instance, with a space gun with a vertical "gun barrel" through both the Earth's crust and the troposphere, totalling ~60 km (37 miles) of length (), and a velocity enough to escape the Earth's gravity (escape velocity, which is 11.2 km/s or ...
The standard ammunition mixture for anti-armor use is a five-to-one mix of PGU-14/B Armor Piercing Incendiary, with a projectile weight of about 14.0 oz (395 grams or 6,096 grains) and PGU-13/B High Explosive Incendiary (HEI) rounds, with a projectile weight of about 13.3 oz (378 grams or 5,833 grains).
