The mystery of Earth's invisible, life-supporting power Alanna Mitchell's globe-trotting history of the science of electromagnetism and the Earth's magnetic field--right up to the latest indications that the North and South Poles may soon reverse, with apocalyptic results--will soon change the way you think about our planet. Award-winning journalist Alanna Mitchell's science storytelling introduce intriguing characters--from the thirteenth-century French investigations into magnetism and the Victorian-era discover that electricity and magnetism emerge from the same fundamental force to the latest research. No one has ever told so eloquently how the Earth itself came to be seen as a magnet, spinning in space with two poles, and that those poles have dramatically reversed many time, often coinciding with mass extinctions. The most recent reversal was 780,000 years ago. Mitchell explores indications that the Earth's magnetic force field is decaying faster than previously thought. When the poles switch, a process that takes many years, the Earth is unprotected from solar radiation storms that would, among other disturbances, wipe out much and possible all of our electromagnetic technology. Navigation for all kinds of animals is disrupted without a stable, magnetic North Pole. But can you imagine no satellites, no Internet, no smartphones--maybe no power grids at all? Alanna Mitchell offers a beautifully crafted narrative history of surprising ideas and science, illuminating invisible parts of our own planet that are constantly changing around us.

Shortlisted for the 2018 Science Writers and Communicators of Canada Book Awards Shortlisted for the 2018 Lane Anderson Award Our future might be a world without electronics or protection from lethal solar radiation The magnetic North Pole will eventually trade places with the South Pole. Satellite evidence suggests to some scientists that the move has already begun, but most still think it won't happen for many decades. All agree that it has happened many times before and will happen again. But this time it will be different. It will be a very bad day for modern civilization. Award-winning science journalist Alanna Mitchell tells in The Spinning Magnet the fascinating history of one of the four fundamental physical forces in the universe, electro-magnetism. From investigations into magnetism in 13th century feudal France and the realization six hundred years later in the Victorian era that electricity and magnetism were essentially the same, to the discovery that the earth was itself a magnet, spinning in space with two poles and that those poles aperiodically reverse, this is an utterly engrossing narrative history of ideas and science that readers of Stephen Greenblatt and Sam Kean will love. But the recent finding that the Earth's magnetic force field is decaying ten times faster than previously thought, portending an imminent pole reversal, ultimately gives this story a spine tingling urgency. When the poles switch, a process that takes many years, the Earth is unprotected from solar radiation storms that would, among other things, wipe out all electromagnetic technology. No satellites, no internet, no smart phones--maybe no power grid at all. Such potentially cataclysmic solar storms are not unusual. The last one occurred in 2012 and we avoided returning to the dark ages only because the part of the sun that erupted happened to be facing away from the Earth. One leading US researcher is already drawing maps of the parts of the planet that would likely become uninhabitable.
