heal.abstract	In this thesis the design of a novel, efficient high-speed electromagnetic mass accelerator is proposed and analyzed. To do so, a theory is put forth to investigate the way electromagnetic force is produced, as well as the parameters that affect it the most. To investigate its validity, the theory was applied for the analysis of classic electromechanical devices such as the induction and dc motors, as well as for Thompson’s jumping ring apparatus. Structural and thermal analyses ensue, to examine all aspects of the device’s operation, as well as to envelope its operation and show its all-round behavior. Finally, high power switches were discussed, which make the operation of the device possible and an automatic (passive) switch design was put forth to be used for the device. It was concluded that this device stands as a solid alternative for a conventional railgun or an induction coil-gun solving some of their most important drawbacks. Nevertheless, as for all mechanical devices, the drawbacks of this device were discussed, and methods to mitigate them were proposed.	el
