Earth's magnetic field is widely understood and modeled as being generated and maintained by convection currents and fluid motion within the liquid outer core (the geodynamo).

The analysis

The claim aligns with well-established geophysics regarding the geodynamo, supported by simulation and theoretical papers in the literature showing that outer core convection generates Earth's magnetic field.
