- Electromagnetic Coilgun Design - Learn about electromagnetic coilgun design principles. These web pages describe theory, design and a small prototype. What is a coilgun? It accelerates a piece of iron or steel down a tube. The tube runs through a series of electromagnetic coils (like solenoids). Some careful timing circuits energize each coil in sequence. The principle of magnetic attraction draws the projectile along at rapidly increasing speed.
