UNAWE Space Scoop - Mapping the Earth’s Magnetic Crust

http://www.unawe.org/kids/unawe1710/ Earth is surrounded by a huge cocoon that protects us from the dangerous cosmic radiation and particles that bombard our planet. Without it, life as we know it would not exist, yet it's totally invisible! This cocoon is Earth's magnetic field. It's more of a magnetic shield than field, if you get my drift!
