Více o knize

North is north and south is south. Or is it? Every once in a long while, the Earth’s magnetic poles switch places. It’s happened many times in deep history, but never since humans walked the planet. After the next big switch, our compasses will point the wrong way and we will no longer be able to see the aurora borealis in Iceland. But that’s not all. It might just push us back into the Stone Age. Beginning with the first investigations into electromagnetism, The Spinning Magnet charts a fascinating history of one of the most powerful forces in the universe. Award-winning science journalist Alanna Mitchell reveals how the Victorians made their pivotal discoveries, delves into unseen and unforeseen natural forces that threaten our planet, and warns of a possible future where solar radiation storms wipe out power grids and electronic communication across the globe.
