Here’s an interesting project for those with some extra time: a rapid fire coil gun. Video demonstration after the jump.
The combination of armature, coil, spring, and housing mixed with pulsed voltage produces a hard hitting injector. The injection force must be strong to counter act the tension extered on the projectile from the magazine spring. The initial projectile speed must be fast to prevent jamming in the accelerator breach
