Magnetic Storm - Trailer

What is weakening Earths invisible shield? Magnets have the power to attract and repel—sometimes on a massive scale. The Earths molten core—a violent mix of searing heat, crushing pressure, and a billion trillion tons of liquid iron—creates an invisible shield that surrounds the globe, guarding against a constant barrage of deadly radiation from space. But over the last few decades, the Earths magnetic field has weakened dramatically, intriguing scientists across the globe.

The power generated 2000 miles beneath our feet protects us every day, but the loss of Earths magnetic field is a brewing storm that affects us all. While experts research and debate, persistent questions remain. Is a rare geomagnetic reversal the cause of earths inner turmoil? And if the magnetic field were to vanish altogether, would Earth become as lifeless as Mars?

Travel from Hawaiis molten lava flows to the mountains of Oregon and into the far reaches of outer space for a charged look at Earths magnetic history and potentially deadly future.
