Multistage Coil Gun
This project shows the basic use of electromagnetic force to propel a projectile ball faster and faster through multiple coils that are fired as soon as the projectile reaches the next coil. This design has not optimized the timing or "suck back" effect, and is merely to show the fundamentals of how a coil gun operates.

What are the components of an electromagnet?
The device typically consists of an electromagnetic coil, capacitor, switch, barrel and movable core - projectile. The coil can be wound as a solenoid electromagnet with a ferromagnetic projectile placed at one of its ends (starting position). The launching process can be divided into three phases. The situation can be reflected in Fig.1.
How does a magnetic coil work?
An intense transient magnetic field is generated in the coil and through interaction with the metal work-piece; pressure in the form of a magnetic pulse is built up to do the work. Data on formability of two aluminum alloys employed for exterior (6111-T4) and interior (5754) automotive body panels will be shown.

The electromagnetic field of the ejection coil was modelled by FEA (see Fig. 3). cca 12,5 mH (with no ferromagnetic materials). With consideration of the higher, i.e. 30,8 mH. This effect causes a variation of time constant during the projectile launches. The force acting on the projectile at its different positions can be seen in Fig. 4.
