My second Thompson Coilgun Model is allmost twice as efficient as the first, and all I did was
made the Coil Legnth shorter by 1/2 of modedl1. This would put the same amount of magnetic flux
on a smaller area, intensifying the force on the steel rod and projectile. Also I had madee the
wire legnth slightly longer by 6ft, my purpose here was to try and increase the pulse legnth slightly
effecting the projectile for a longer duration.
