DIY Coil Gun

The basic principle behind a Coil Gun is that a current carrying conductor will induce a magnetic field around it, which was stated by Faraday. To improve the strength of this magnetic field the current carrying conductor is wound in form of a coil. Now, when this coil is powered it produces a magnetic field around it which is strong enough to attract metal (or other Ferro magnetic) pieces a.k.a projectiles into it.
