Induction Coilgun Based on “E-Shaped” Design

Abstract

This paper describes a device capable of throwing aluminum rings in a range of a few meters. The device is a modification of the jumping-ring design invented by the American engineer and inventor E. Thomson to demonstrate his pioneering research in alternating current. We improved the magnetic circuit of this device and created a new induction coilgun based on “E-shaped” design. We experimented with this new design under laboratory conditions and simulated its behavior using an interactive software package. Finally, we concluded that this device is able to achieve a higher speed than the Thomson design with lesser power consumption.
