propelling metal |
|
|
Does anyone know any devices (such as ion ray guns) that can push
metal away instead in your direction like an electromagnet?
any advice would be appriciated
thanks!

First off, in your direction is a bad idea!!! |
While I do not recommend building one for fear you will kill your self or
some one else.. I have seen this done with a bank of very large
capacitors each attached to a ring electro magnet.. the rings are spaced
to compensate for acceleration along outside of a tube the diameter large
enough for your projectile to fit in of course.
The capacitors are all fully charged, firing involved discharging each
capacitor in turn into it's respective coil, this takes careful timing.
Each coil attracts the projectile, and is designed to be fully
discharged; by the time the projectile reaches the coil, then the next
one and so on.
Any way if you have the skills to put something like this together, then
I don't think I need to warn you of it's dangers.
if you really must puch, then use a magnet. I think some shot gun pellet
metal is anti magnetic but I can not remember what it is called.

That's a 'rail gun' you're describing, isn't it?

Hmm, an electromagnetic cannon...
One can either push or pull.
Induced eddy currents in aluminium will oppose the driver current, and thus
be repelled.
You can push-launch aluminium rings off a pulsed coil that way.
IIRC antimagnetic effects (barring superconductors) are far weaker than
magnetic ones, so pulling seems the best bet.
Especially since you can easily get ball bearings.
One refinement might be to have coils trigged by the ball breaking light
beams.
That way they fire whenever it is in the right position.
Of course you could also stuff enough energy in so the eddy currents heat
the ball bearing into plasma.
I don't know what UK gun laws say about personal plasma cannons.
But the USA loves guns like the middle east loves swords, so you could rack
up a huge electricity bill at the local NRA shooting range. It might be
lethal to anyone with a pacemaker, you don't even have to point it at them! |

Describe the situation in more detail please.
There are methods for propelling pieces of metal away that have been
used for years. About 250 grains of powder will do a pretty good job
with a .50 cal BMG round.
