Coil Tattoo Gun by Elizabeth Vasquez in Logo Design Ideas & Inspiration Want to know why and how electromagnets work? A coilgun uses a series of electromagnetic coils to accelerate a ferromagnetic projectile. Check out CoilGun Systems for a very detailed write up of the CS-Po1A. Tracking means how good a gun is at predicting where the enemy will move next and adapt accordingly. One main obstacle in coilgun design is switching the power through the coils. This program models the behavior of a ferromagnetic projectile under the influence of magnetic induction. More info and a video to follow. This coilgun is a bit more tricky than a railgun because it requires multiple sections to turn ON and OFF at very precise times. Coilgun experiments often run on high voltages so there's a pretty great chance you'll get electrocuted. A railgun simply uses one big burst of power to launch a projectile; a coilgun uses a series of electromagnetic coils. It requires no volatile propellant and can easily be fired at any unlimited time, providing that there is a quantity of bullets. Another homemade coil gun design. Take a look at the graph below, it shows the net internal field along the axis of two projectiles - one 20mm long x 10mm diameter and the other 10mm long x 10mm diameter. Our purpose is to obtain algebraic expressions which, although crude, provide useful predictors of behavior, illustrate the dependence on various parameters, and suggest ways to optimize the design.
