    I was having a class on Physics when out of nowhere emerged the thought: "Why can't we have guns without gunpowder?"

    I kept thinking on a solution. And I thouht about something that, in my mind, made sense:

    1) Get two long, rectangular magnets. (About 1 Metre each)

    2) Carve a semi-cricle in each, so that their concave parts repel each other (negative and negative or vice-versa). Make it so that when put together, the concave parts form a tube runs through them.

    3) Tape them tightly together, allowing a repelling field to be created inside the tube.

    4) Insert a Metal ball in the tube and push it with a wood stick until it reaches the middle of the tube.

    5) The ball should fly out, the other way, with a great speed.

    What do you guys think? Would this work? Should I test it? Please comment.

    1) You don't have the materials or expertise to attempt it.
    2) The world doesn't need anymore high powered projectiles.

    Hahaha. Expertise? You're an idiot. How much expertise is needed to drill a hole and tape two bars together?

    I'd imagine it would require more than you posess at any rate.

    I don't know how it works where you live, maybe you're a secluded hermit who lives inside a cave, but for us, normal people, a piece of tape and a magnet are not difficult items to acquire. If you want to criticize my idea, go ahead, but don't tell me I can't get the materials. In fact, I have already seen the magnets on a store close to my house, but as they were expensive, I would rather know if the idea worked.

    I don't know how it works where you live, but for us, normal people, we tend not to be able to find massive, powerful magnets which are over a meter in length in our local shops. Nor do we think about making guns.

    I DIDN'T ASK YOU FOR YOUR THOUGHTS ON MY LOCAL STORE, I WAS ASKING YOU IF, HYPOTHETICALLY, WOULD THIS WORK?

    It would not work. The ball might be moved somewhat out of the barrel. I can't quite envisage how the field lines would run in your set up, but you would scarely achieve the velocity to inconvenience and anemic tadpole. You would be better off thinking about mass drivers.

    Sox, just because montysire has a dumb idea it doesn't mean he is dumb. I advise both of you to drop the antagonism before a mod comes along and does it for you.

    I don't think he's dumb. I think he lacks the expertise. Expertise is acquired.

    Ok, so, I mean, should I try it out? In small scale?

    No, it wouldnt work.

    Even a relatively strong magnet wouldnt be able to achieve the speeds you want it to.

    I might've passed the wrong idea. I'm not trying to shoot the ball through fifteen aligned brick walls, I was looking for something able to go through a wooden door, nothing more than that.

    The answer would still be no. You'd have to have magnets bigger than those you could fit into a gun.

    I've already said it wouldn't scare an anemic tadpole.

    Sox has said don't waste your time

    Twit of wit has said No.

    What clearer message can we give? Hello! Anyone at home?

    It won't ****ing work.



    Now it was actually a clever idea. Conceptually excellent: let's use magnetism - which moves things - to move a small object quite rapidly. You've even attempted some mental rudimentary engineering. It's just unfortunate that the damn thing won't work. Now move on and use your imagination for something else.

    There are already a lot of designs for guns without gunpowder. Rail guns, coil guns, etc. Just look up magnetic gun on Youtube. Notice that none of them use just a static field and a bullet. It takes more than that to make a gun. (Also, the magnets may repel each other, but they'd still attract the bullet.)

    Impeccable opinion. I wholly agree.

    Electromagnetic cannon have been constructed, they are called rail gun's. They are a series of electromagnets. They are huge, heavy, require massive amount's of energy. They also require precise computer control on the level of nanoseconds. If the length's of power, and com cords, are not precise to micrometer's, the device won't work.

    If you want to construct a "fun" projectile weapon, I recommend an "Idaho Uzi", or also called a "spud gun, or potato cannon". The construction of one is easily researched. Just remember, all projectiles are dangerous! And even "hobby" devices can be subject to local, state, and or federal regulations.

    What do you guys think? Would this work? Should I test it? Please comment.
    1) Why would you expect the ball to exit at high speed or at all ? What force would propel the ball along the axis of the "barrel" ?

    2) Electromagnetic guns have been and are being evaluated in research labs. They generally work by induction and do not use permanent magnets. They also are not very efficient as they currently exist, but have potential for high velocities with more research.

    Contrary to what sox said, there is in fact great interest in anything that provides significant increase in muzzle velocity for guns, particularly large guns. It is important for anti-armor and long-range artillery applications.

    However, your idea will not work.
