Details

The science journalist Alanna Mitchell explores an aspect of our planet that we take for granted as unchanging, yet Earth’s electromagnetic field is critical and the poles that seem so fixed can switch places; the last time they did so was 780,000 years ago. Beginning with the discoveries of the Victorian scientists who pioneered the modern understanding of magnetism, Mitchell investigates the science of this powerful phenomenon and what it could mean for the future of Earth.
