Essentially, this sounds like a rail gun.
Taken to a much larger scale, such devices are capable of projecting small
aluminum or heavier metal slugs at speeds capable of reaching thousands of
miles per hour (in theory sufficient to place small objects into low earth
orbit).
Ignore the G-forces on launch and the atmospheric frictional heating on the
launched objects. Also never mind the fact that they take megawatts of
electrical power to do so... they are possible.
