Electromagnetic Accelerator Improvements Part I - Gauss Cannon test rig

In this video I experiment with different improvements to electromagnet coils and build a test fixture to measure my results and compare them to magnetic finite element simulations.

Ultimately, i measured an efficiency increase of 51% on a coil that was covered in a shell of ferrous material acting as a magnetic flux guide.

The magnetic simulation software i use is called FEMM 4.2 and it's free to download: https://www.femm.info/wiki/HomePage
