WebApr 9, 2024 · The outer core consists of molten iron, while the inner core has the solidified elements. The motion of the electrically conducting iron in the presence of the Earth's magnetic field induces electric currents. Those electric currents generate their own magnetic field, which amplifies and sustains the overall magnetic field. WebAug 2, 2024 · Rusting of iron is a process that involves oxidation and reduction. Oxygen is reduced, while iron is oxidized. While it's easy to identify which species are oxidized and reduced using the "oxygen" definition of oxidation and reduction, it's harder to visualize electrons. One way to do this is to rewrite the reaction as an ionic equation.
