Question

Quizplus · Accepted Answer

The Earth's magnetic field is thought to be generated by the movement of molten iron and nickel in its outer core, which creates convection currents, combined with the rotation of the Earth. This process involves moving charges, as these metals are conductive, and the movement of a conductive fluid generates a magnetic field. Thus, all the options provided contribute to the explanation of the Earth's magnetic field.
