Our four stage magnetic accelerator assembles in minutes without tools or glue. It includes powerful rare-earth magnets, steel ball bearings, a 22cm (8.5″) long firing trough, and all the hardware needed to build your own magnetic accelerator. You can even join more than one kit to multiply the effect! This kit is an ideal centrepiece for a science project on magnetism and kinetic energy.

All of our products are manufactured on-site at our facility using quality Canadian lumber and locally sourced hardware. There is no lead in any of our products.

Background Information

A magnetic cannon is a chain reaction device. It is built in a series of stages, each containing a magnet, a spacer, and a projectile. To start the chain reaction, a steel ball is released, which accelerates towards the first stage magnet. Like billiard balls, when it strikes the magnet, its energy is transfered through the magnet and spacer and into the projectile which speeds off toward the next stage. The process repeats until the last projectile leaves the end of the device. The more stages an accelerator has, and the more powerful the magnets are at each stage, the faster the ball bearing will leave the final stage!

This type of cannon can also be called a “magnetic accelerator”, “magnetic rifle”, “gauss rifle”, “linear gaussian accelerator”, or “linear chain reaction magnetic accelerator”.
