This model was made from a single coil into 4 coil forms from just a idea of mine that I knew could work. Other's said that the idea of multiple coils from a single wire would not work and would act as a single coil, but common sense told me that each coil would act as its own coil and have its own center which to pull or push "attract" the projectile. And so I have proven my theory correct by designing and creating this model.
