Can RAILGUN fire at low electric current?
I have been reading a lot of articles about Railgun and how it consume a lot of power to launch a high speed 20 km/s projectile. So my question is, can you use a low power current and still fire the projectile but at lower speed? Or is that impossible because thats not how it is going to work? Thanks.
So you the Lorentz force still work at any currents?
Answer: basically the power is a function of I^2, and so the kinetic energy is MUCH less at lower currnts

Need instructions on how to build a RAILGUN or coilgun?
Yes, I know the difference between them.
Id like to build a Railgun, but that is probably prohibitively expensive for me. Ill settle for a less powerful coilgun.
Since this is my first time ever doing anything like this Ill need complete instructions, including how to make a multiple stage coilgun later.
Input from anyone who has built these before would be much appreciated.
Thanks.

Can anyone give me a decent thesis or essay on why silver could not be used in a RAILGUN?
I do actually know that it cannot be used in a regular gun, as the silver is too hard and compresses differently than lead, causing backfires and explosions.
This is a matter of life and death.
Answer: Do you understand what a rail gun is?
http://en.wikipedia.org/wiki/Railgun
Your question is way to vague to answer! What part of a rail gun are you proposing to use silver for? I suspect it is fine for some components and not for others.
I don't understand what you mean by 'backfires and explosions' ? A traditional Railgun is an electromagnetic acceleration device that uses no explosives, propellants or deflagrants and thus has no mechanism for backfiring. It releases a lot of energy in a short period of time for sure, but I'm not sure where the word 'explosion' comes in? The forces of a rail gun can be self destructive. Capacitors, I suppose, could explode? But how this all related to the use of silver is ... ???
It bothers me (and probably everyone else) greatly that you indicate "This is a matter of life and death". Yahoo answers is not the place to turn for information on life and death matters!

How much armor would it take to stop a RAILGUN?
If you mounted a Railgun on a spaceship for use against other vessels how much stell or titaniaum plating would it take to stop a 70 pound projectile fired at 11000 feet per second?
Answer: Technically, you would not be able to stop it at all. It's more than massive firepower. It will either rip right trough the vessel or it will tip it over due to it's massive force.

Does it matter what order you watch To Aru Kagaku no RAILGUN and To Aru no Index?
Ive been watching To Aru Kagaku no Railgun (im on ep 17) but my roommate just told me that there was a series before it. however Railgun seems to be its own story. My roommate hasnt seen Railgun yet so i was describing a bit of her to her and she thought it might possibly be a prequel to Index that they made afterward but were not sure. Anyone know?
Answer: It really doesn't matter. I did the same thing as you; watched To Aru Kagaku no Railgun first because it was more anticipated. After that, I watched the first season of Majutsu no Index and they're really different stories. Theres no connections between then, and Railgun is a spinoff.
I only watch Majutsu no Index to see Biribiri x Touma interations anyways ^.^

RAILGUN or Kitty? |

Could a RAILGUN fire a space faring ship as a projectile if the gun was large enough and the ship shielded?
In Mass Effect they rely on the tech of an ancient race. To move at extreme speed they use a "station" that "flings" a ship and it then travels at faster than light speed. It seems similar to a Railgun to me but I have doubts that the ship or the crew would survive such a perilous journey. Could it ever be possible to utilize a Railgun for such a purpose.
Answer: Typically, a Railgun is an electromagnetic accelerator that causes a massive current to be routed between two rails, through the projectile. It's very effective at launching projectiles at high speeds, although certainly not faster than light. The current induces a powerful electromagnetic force, called the Lorentz force, and magnetically accelerates the projectile down the length of the two rails, keeping the current flowing between them until it leaves the vicinity.
In theory, there's no reason why, with enough advances in superconductors and special insulation, a Railgun couldn't launch a space ship. There are a lot of design problems, however, with scaling up a Railgun to launch projectiles!
A more likely approach would be a linear magnetic accelerator, much like the ones found on some roller-coaster rides. These, instead of routing current through the "projectile," use electromagnets switched on in series to accelerate the projectile.
Short answer: Yes, a Railgun should be able to fire a space-faring ship as a projectile... but we have a long way to go before it would be practical, and the Railgun principle alone will not get a ship to exceed the speed of light.

How do you calculate the force of a RAILGUN?
How do you calculate the force of a Railgun, if you have one built and you knew the voltage, amperage and resistance of the armature and the rails.
well i know that, but my friend proposed a double helix rail, that imcreases length of the rails without increasing the length of the barrel. so is lenght the barrel length or the rail length.
also, how do you find B?
what is it measured with?
Answer: You need to know the strength of the magnetic field, but the equation is:
F = I*L*B
Where I is the current through the armature, L is the length of the armature and B is the strength of the magnetic field (this is assuming the magnetic field is perpendicular to the armature). You can look up 'Lorentz force' for more info if you like.
EDIT: The length that is important is the length of the wire connecting the two rails (or equivalently, the distance between the two rails). I'm not sure I understand what you mean by a double helix rail, it seems like the armature would be very unstable if it was riding on top of a helical structure (unless its riding 'in' the helix? But that would cause other problems).
As for measuring B, it's quite difficult unfortunately. If you're using electromagnets, you might be able to calculate B using the Biot-Savart law:
http://en.wikipedia.org/wiki/Biot_savart
If you're using permanent magnets, it's probably not worth the troubling of trying to calculate the value of B. If you really need a specific number for it, then you'll probably have to fire the rail gun and measure the force it applies (using a force gauge for example). Knowing the force applied (and the current applied and the length of the armature) you can calculate B.

In theory, I was wondering if you used lighting to power a RAILGUN, how may joules would it create?
In chemistry, we are do independent projects, and I was looking into a Railgun for fun. Then I thought, "what if you powered one with a lighting bolt?" I know it would be incredibly stupid to try, but I was wondering. I think a lighting bolt has like 100 million volts.

Lightning is static electricity, not AC or DC electric current.
If the lightning struck a lightning rod, and the other end of the lightning rod was attached to a very large capacitor, the capacitor would store the electrons with a potential difference of 100 million volts.
100 million volts would produce enough electric current to FRY the Railgun.
Now, you will need a voltage regulator to produce an output voltage that the Railgun can use.

What would it take to build a small-scale RAILGUN?
In my High school engineering class, we are working on a Rube Goldberg machine. My portion involves shooting a balanced basketball with a small rail gun to make it go in the hoop. As such, I am hoping I can get specifics on what it will take.
The gun will probably launch a quarter (or a stack if one quarter isnt heavy enough). What kinds of batteries or power supplies will get me what kinds of force?
Answer: A rail gun is a pretty sophisticated device---The precision machining and the cost of the materials put it beyond the reach of most hobbyists.
http://en.wikipedia.org/wiki/Rail_gun
You'd find it much easier and cheaper to build a magnetic ring cannon. You can even buy them in kit form, though I don't know if you'll find a kit that delivers enough energy to shoot a basketball.
