Here’s a short presentation that will show you how to build a miniature version of a traditional gaussian gun. But first, what is a gaussian gun? According to wikipedia, it is a type of magnetic accelerator gun that uses one or more electromagnetic coils to accelerate a magnetic shell to very high velocities. Full-sized gaussian guns are usually built out of a few large capacitors and a circuit breaker, but for the mini version, we’ll only use six steel ball bearings and two neodymium magnets to power the device up.
And now that you know how to make your own miniature gaussian gun, here’s a short clip that will show you a real one in action.
