+ | As the last of the new power lines were assembled, scientists at the Hawkion research facility made a hypothesis that the EM-boar tiger originally tore the lines down because it didn't like the magnetic field that the wire produced. Maybe magnetic field is something Lakeview can use to defend itself! | ||
+ | |||
+ | Now that the power is back on, the people of Lakeview are itching to get back to using its extensive subway system to get from place to place. Before the town opens up access to the subway system again, Lakeview' | ||

+ | You and your team comply and descend into the subway system. You notice a bright blue glow coming from deep in one of the subway tunnels... Yup, it's definitely a pack of hungry EM-boar tigers, ready to munch on a subway car or something. You immediately radio up to Dr. Natkins to see what you should do. He explains that the wiring embedded in the walls of the subway tunnel are arranged just like a big solenoid. | ||
+ | |||
+ | The tunnel is 1 km long, and Dr. Natkins estimates there are about 8,000 coils of wire from one end of the tunnel to the other. Based on from what you can see right now, the tunnel looks to be about 10 meters wide. Dr. Natkins says that if you can tell him a value for the current needed in the solenoid' | ||
