Earth’s Magnetic Field

Earth’s core may have hardened just in time to save its magnetic field

Earth’s inner core solidified around 565 million years ago — just in time to not only save the planet’s protective magnetic field from imminent collapse, but also to kick-start it into its current, powerful phase, a new study suggests.

Combined with previous studies that have found that the magnetic field was also rapidly reversing polarity during that time period, the new result indicates that Earth’s field may have been on the point of collapse about 565 million years ago. That suggests that the inner core hadn’t yet solidified. Fortunately for life on Earth, it eventually did.
