Part 7/10:
As the conversation progressed, distinctions between existing geological models and Peter's theory emerged. The predominant belief is that the Earth has an iron core responsible for generating its magnetic field. Peter contested this by proposing that the Earth might not even need an iron core to maintain its magnetic properties. Instead, he argued that the electrical currents generated by the Earth’s rotation could suffice.
Moreover, Peter suggested that the assumption of Earth's core being solid is flawed and that the mantle might contain more liquid than previously thought. This leads to new implications on how we understand Earth's internal structure.
