I was looking at the lunar eclipse last night -- cool shit... but then I started wondering about the Earth's magnetic field... Sure the icecaps are probably based on exposure to light... and the Earth has an iron core? And the magnetic polarity of Earth changes every 100,000 years or some shit -- but I still don't know how the fucking Earth got magnetized...

I remember in 1st grade I made an electromagnet -- a big nail with a coil of wire and a big ass battery... Did somebody wrap a big wire around the earth -- magnetized it -- and then vanished into space?
