Gauss Gun (Coil Gun) demo



A gauss gun, works by sequentially accelerating a projectile to a desired speed by using either magnets or coils.
Simplified coilgun diagram with three coils, a barrel and ferromagnetic projectile. Each of the coils is connected to a fast discharge energy storage source (capacitor bank) and activated in sequence by a timing device thus producing a strong magnetic field causing the rapid acceleration of the projectile.
The first video is a small demonstration of the principle behind the whole thing, by using magnets. The following videos are weapons which were homemade, and as you can see work remarkably well. So well in fact, that the US Navy will implement such weapons on its ships by 2020, after they succesfully tested an 8 Megajoule prototype.

Comments for Gauss Gun (Coil Gun) demo

Wow!

The Gauss gun has always interested me, I'm actually trying to build one atm, man, quite complex.
Loved the clips, the first one showing how simple it really is, it helps you see the physics involved, the second, a home made one and it's effectiveness and, alas, charging time flaws, and the third shown the devastation of it, just imagine if that potato was someones head!
