Mini Gaussian Gun

I don't have an neodymium magnets, but it looks like a neat trick. Can anyone explain why or how it works??

The setup makes it look like the first ball bearing is going quite slow, but it actually is going the same speed as the bearing propelled off the end when it hits the magnets. The extra ball bearings are inbetween the magnets and the projectile ball bearing to weaken the feild the magnets have with the projectile, and transfer the kinetic energy.

the input speed and the output speed are not the same,
potential energy is stored in the setup.

Reminds me of the newtons cradle.
Just think of it as that, except the neo magnets are what attracts the first ball bearing, and the neo magnets are part of the newtons cradle. The long strip of bearings after the magets mean that there isn't much of a force holding that last ball back, so off it flies.

True, still any speeds/forces greater then those involved in a small CG will shatter the magnets.

What about having a slidable box around the magnet, so the bearing hits the box, and transfers energy through that?

This was discussed in quite a bit of detail on the old forum.
I was decided that to get any resonable power out would involve shattered magnets. Ideas for protecting the magnets were mainly focused arround putting a decently thick piece of metal arround the magnet, which would decrease the feild, killing efficiency.
