| well , when you put the high voltage pulse through the rails the foil vaporises into plasma, and creates a very strong magnetic field, shooting the plasma out. |

| How do you know wich way the foil will go?Do you think it is possible with 10v 650 000mf? |

@Rambo: The magnetic field is generated following the cork rule (if I remember from years ago in Physics) you'll figure it out if you read PpowerLabs' articles on them: http://www.powerlabs.org/railgun.htm
@Benny: If the foil vaporises, the magnetic field will have nothing to pull. Plus, this is a KE (kinetic energy) gun. Energy=mass*speed. How much mass do you think a molecule of aluminium has? Hint: by far not enough to be used as a projectile unless it has speeds aproaching that of light.
As a side-note: Particles (albeit heavier than Al) have been accelerated to energies equal to a bullet. Yet these particle accelerators are as big as a city block and use just as much power. What I'm trying to show you is that a plasma gun like the one Benny is talking about would be REALLY, but I mean REALLY impractical. Railguns shoot solid proijectiles, period. |

Yes, but only for 1/3 of a second and at limited range (perhaps 3 feet for the Powerlabs railgun). So having a quarter-ton 5-foot-long railgun to ignite matches 3 feet away is pretty stupid. You could do the same with 3 grams of gunpowder.
The site talked about graphite slugs. Sounds to me like industrial motor brushes (solid graphite ones) would make a great projectile. Of course, you'd need a pretty big railgun. |

this rail gun he made is just to demonstrate how it works for a cheap price, it is really mad      |
