How to make Mikoto Misaka?

For anyone unfamiliar with her character, she is a powerful electromancer. Besides blasts of lighting, she usually fights by pulling iron particles out of the earth to make vibrating weapons. And of course, there's her railgun which has her launching a coin down a magnetic rail that she makes herself!
