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. [1]
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.
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.
Coilgun, 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 Railgun , a linear motor device that uses electromagnetic force to launch high-velocity projectiles
The Arcflash Labs GR-1 "Anvil" is a portable shoulder-fired semi-automatic bullpup 8-stage coilgun designed and manufactured by Arcflash Labs in Los Angeles, California. [1] [2] It is the most powerful handheld coilgun ever sold publicly. It was developed 3 years after the EMG-01A. [3]
The projectile is energized continuously by two brushes sliding along the rails, and two or more additional brushes on the projectile serve to energize and commute several windings of the helical barrel direction in front of and/or behind the projectile. The helical railgun is a cross between a railgun and a coilgun. They do not currently exist ...
The E-Shotgun, also referred to as the E-Gun, Northshore Sports Club CA-09, [1] [2] or the PD-90 Advanced Coilgun, is a hand-held automatic 9-stage coilgun designed by Lei Fengqiao and manufactured by China North Industries Group Corp [3] in Xicheng District, Beijing, China (as well as "other technology teams").
To be a coilgun it has simply to be a device intended to accelerate a projectile using an attracting (or conceivably repelling) electromagnetic coil. If the 'gun' accelerated the projectile using an electromagnet that wasn't a coil one could argue that the gun technically isn't a [i]coil[/i]gun, but that's truly a semantic argument.
