Ecuson Model <Top — 2024>

To understand the Eccles-Kutzler model, one must first appreciate the environment it seeks to describe. The Earth’s outer core is a fluid shell composed primarily of molten iron and nickel. It is a region of intense heat, high pressure, and complex fluid motion. The mainstream scientific consensus holds that the movement of this conductive fluid generates the Earth's magnetic field through the dynamo effect. However, early models struggled to fully explain the specific coupling between the solid inner core and the fluid outer core, particularly regarding the transfer of angular momentum and heat.

In a standard fluid dynamic model, the friction between a solid boundary and a fluid is predicted by the viscosity of the fluid. However, seismic data suggests that the Earth's outer core has a very low viscosity, similar to water. If viscosity were the only factor, the solid inner core should rotate almost independently of the fluid surrounding it. The Eccles-Kutzler model addresses this discrepancy by introducing the concept of electromagnetic torque. To understand the Eccles-Kutzler model, one must first
