Earth's magnetic poles are maintained and positioned by convection currents in the liquid outer core
the verdict
SUPPORTED
the evidence backs this
confidence 75/100
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).
