Electromagnetic Propulsion Electromagnetic propulsion may sound like a lofty idea, but it is really something that is quite common in one’s everyday life. Electric motors, high-speed particle accelerators, levitating trains, the Superman ride at Six Flags amusement park, and most high load electrical switches all use electromotive force. Electromagnetic propulsion may also be the next step big step in space travel. The cost of using chemical propellant to put objects into orbit is approximately 8,000 …

…coils reduces resistance by up to a third (Barros). Decreasing resistance increases magnetic field energy by increasing current. While coil guns may not be as efficient as deflagrating gunpowder, it is definitely cool to think that one can fire high speed projectiles silently using only some wire and a power source. If more research is done and efficiency is increased, asynchronous linear induction motors could definitely revolutionize transportation, weaponry, and all sorts of other industries.
