Actually, I believe this is how Mikoto's railgun is set up (quoting my post from the Touma's Power: What can he block ? thread):

  • The projectile is the coin, obviously. As it is made of conductive material, then it also serves as the armature.
  • She is the power source.
  • The rails are not really rails. Instead, she summons two (four even) parallel electrical currents going in opposite directions.
  • Somehow she is able to control these currents perfectly such that they are traveling along the same length and are able to stay on their initial positions. No wonder she's a Level 5 -- if maintaining such conditions are easy enough, then we would be seeing at least Level 3 electromasters shooting high-velocity railguns.
Now, what happens when the circuit is closed (when the coin is tossed into the system)? The Lorentz force created by the current accelerates the armature away from the power supply. In traditional rail guns, the recoil effect is in the form of the rails pushing at the breech, as said above. Here, the resulting recoil force accelerates air occupying the area where the current is flowing (which is accounted for in all illustrations so far), causing a gust of wind flowing towards Mikoto (and continuing behind her, etc.). Reasons why this is not dangerous to her (as someone who has complete control over the system) should be obvious.
