The Idea
Another egg about magnets from me. This time it shows how to build a linear magnetic accerator. This is sometimes referred to as a Gauss Cannon or a coil gun. My rig did not work as well as it could’ve because of my magnets strange shape. These are the only neodynium magnets I had, therefore I had to use them. They still work though.
Materials
- Some sort of groove or ridge ball bearing could fit in, without rolling to the sides. I just used the space between two tiles in the bathroom.
- Magnets. Must be relatively strong. Neodynium works great. Best in a disk shape, like this.
- Ball bearings or other magnetic balls.
So to sum it up, you need this.
How To
First, take your magnet, and place it in the ridge so that the north and south poles go in the direction of the ridge. Now place ball bearings at either the north or south end of the magnet. You might want to experiment with how many balls you use. Four works best for my magnets.
Now place a ball bearing a little but behind the side without the group of balls.
Now give it a little push, and it will start rolling towards it, picking up speed, and hitting the magnet, transferring the momentum through the balls, all the way to the last bearing, and it will shoot out like this GIF shows. Works a little bit like Newton’s cradle.
Now if you want to create a chain reaction, just create two sets of magnets, like this.
Push the ball forward once again, and watch it hit the first set, firing off one ball. That ball travels towards the next magnet, and propels another ball bearing out. This can be done with as many sets of magnets and bearings as you wish, but I only had two magnets, and could only do two sets.
Interesting Videos
I happned to find two videos on YouTube about Gauss Cannons.
Please don’t be a dumbass and say OBVIOUS! because some of you might not have known this. And even if you did know, I put in a lot of effort into this egg, especially the GIFS, so please rate fairly.

May 16, 2006 2:59 pm - sweet omg i loved it!! i put it on a ruler with tons of those magnets held tog by tape (this one sites idea) wit lots of those balls and it noked over my clock! u can get some good magnets at magnet4less.com[magnet4le s.com]
