INNER CORE, THEN AND NOW: Earth’s magnetic field is generated in its liquid iron core via a geodynamo. Researchers believe a weak geodynamo—and a weak magnetic shield—formed early in Earth’s history, but decreased for the next several billion years until a critical point 565 million years ago (left image). The researchers conjecture it was at this point in the geological time scale that the inner core began to form, increasing the strength of the geodynamo and the magnetic field (right image).
