It's coilgun. They're very simple in principle, but the engineering challenges are significant. Power limits are also a problem, especially at the beginning of the 20th century. The big benefit is that you don't need to worry about maintaining pressure behind the projectile as the volume behind it expands and it accelerates. That helps when you want really, really fast projectiles because you don't need a massively strong barrel. (You'll still need a long gun, possibly longer than a conventional cannon, but the whole structure can be much lighter.)

If you flip the polarity of the coil instead of just turning it off you double the force on the slug.
