The correct response is: Convection currents moving the iron and nickel in circles in the outer core.
This process, known as the geodynamo, is responsible for generating the Earth's magnetic field. The movement of molten iron and nickel in the outer core creates electric currents, which in turn produce magnetic fields around the Earth.
