"May the great Maxwell bless me!" Rorschach was back in his dorm at the Tower of Stars, desperately trying to recall the contents of his electrical and electronics courses.
The Dwarves had already discovered the principle of magnetism producing electricity, but they hadn't realized the reverse was also true: electricity could produce magnetism. Goes to show how single-minded they could be. Of course, this also meant the Dwarves hadn't discovered electromagnetic waves.
In the lab, Rorschach explained to everyone that while he was investigating the building's systems, he noticed that the instruments measuring Ether fluctuations were picking up a set of interference signals. The spectrogram showed anomalous peaks that hadn't appeared in other experiments within the Tower of Stars, not even in Professor Poincaré's own lab.
Upon further observation, the anomalous peaks appeared when the generator units in the power room were running, and disappeared when they were shut down.
