|Origin of The Earths Magnetism|
This site holds information on the Dynamo Theory, the suspected cause of Earth's magnetic field. The Earth's magnetism seems to come from fluid motions in the Earth's core, from circulating flows that help get rid of heat produced there. The author discusses the Blackett proposal and shows why it cannot be correct. He also points out some of the problems with the Dynamo Theory.
