The Magnetic Field of Earth's Core: What is the Source?

AI Thread Summary
The discussion centers on the origins of Earth's magnetic field, specifically questioning whether it originates from the core and if there is a compelling physical model to support this. Participants reference the dynamo theory, which posits that the movement of molten iron in the outer core generates the magnetic field through electrical currents. Some contributors express skepticism about this model, suggesting that alternative theories may exist and questioning the adequacy of current explanations. Recent studies and satellite data indicate that changes in the magnetic field are linked to the dynamics of liquid iron in the outer core, but some participants seek further clarification on the mechanisms involved. Overall, the conversation highlights ongoing debates and research regarding the Earth's magnetic field and its sources.

Well,
The[/PLAIN] https://en.wikipedia.org/wiki/Earth's_magnetic_field has all information for you

yeah
that was posted a way back in the second post in the thread :wink:

tis always good to read through a thread before posting to save doubling up on the same info :smile:Dave
