Can coil guns kill?

The styling is straight out of a video-game, but inside the engineering is very real, and very lethal. A coil-gun uses a magnetic field to accelerate a bullet up to projectile speed.

Why are coil guns so inefficient?

Coilguns are inherently slow because the inductance of the coils limits how quickly you can build up and destroy a magnetic field, and a large mass can pull energy out of a coil’s magnetic field much more quickly than a small mass.

Do coil guns exist?

There are two main types or setups of a coilgun: single-stage and multistage. A single-stage coilgun uses one electromagnetic coil to propel a projectile. A multistage coilgun uses several electromagnetic coils in succession to progressively increase the speed of the projectile.

How effective are coil guns?

Since the projectile of a coilgun floats in the barrel and never touches the coils, it suffers less wear and tear, and these guns are completely quiet. Coil guns have been demonstrated to supersonic velocities, but they are not as efficient or as capable as railguns.

Are railguns rifled?

No, you cannot have a rifled railgun. A railgun does not have a traditional barrel. The projectile is carried down the “barrel” on a series of rails via a force not unlike linear induction (on steroids). There is no place for rifling.

Do coil guns have recoil?

Therefore, for a coilgun of equivalent power to a railgun, the coilgun’s recoil will hurt more since it is at some points low and at others high… And uneven recoil hurts a lot more than steady smooth force.

What makes a coil gun more powerful?

Coil guns (aka Gauss guns) Have a higher max projectile velocity. Powerful switches alternate the electromagnetic poles in the drive coils as the projectile passes through the coils. This requires high voltage, high amperage, high speed electrical switches.
