to make weapons that fire very rapidly, because you can bypass all the mechanics of getting the bullet from the magazine into the chamber and just line up all the bullets along the EM rail.

Apparently, with the fastest-firing conventional single-barrel weapons, the minimum distance you can get between consecutively fired bullets is about a foot. But with these railguns it's centimetres.
