Anthem Chapter 3

Equality  is fascinated by what he has discovered, and sees that it defies all the currently known laws of nature. He has been taught by his society that lodestones in compasses always point north, but now he sees that the new power makes the needle of a compass move. He also discovers that, in thunderstorms, if he puts a tall iron rod next to the entrance of the tunnel, the iron will draw the lightning. He reasons that the new power causes lightning -- a radically new notion.
