First map of Earth’s magnetic field based on compass readings, by Edmond Halley, after sailing the Atlantic Ocean on the Paramore. Since we now know Earth’s magnetic pole shifts over time, these lines are not stable – scientists update the World Magnetic Model every five years. As of 2019, the magnetic north is moving towards Siberia at a rate of about 34 miles (55 km) per year. (E. Halley/Princeton Library Historic Maps Collection)
