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] In almost all coilgun configurations, the coils and the gun barrel are arranged on a common axis.
The helical railgun is a cross between a railgun and a coilgun. They do not currently exist in a practical, usable form. A helical railgun was built at MIT in 1980 and was powered by several banks of, for the time, large capacitors (approximately 4 farads). It was about 3 meters long, consisting of 2 meters of accelerating coil and 1 meter of ...

Although any device used to propel a ballistic payload is technically a mass driver, in this context a mass driver is essentially a coilgun that magnetically accelerates a package consisting of a magnetizable holder containing a payload. Once the payload has been accelerated, the two separate, and the holder is slowed and recycled for another ...
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 plasma railgun is a linear accelerator which, like a projectile railgun, uses two long parallel electrodes to accelerate a "sliding short" armature. However, in a plasma railgun, the armature and ejected projectile consists of plasma, or hot, ionized, gas-like particles, instead of a solid slug of material. Scientific plasma railguns are ...
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").
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.
