WebApr 9, 2024 · How the Earth's Core Generates a Magnetic Field: The Earth's outer core is in a state of turbulent convection as the result of radioactive heating and chemical differentiation. The flowing molten metal in Earth's core creates an electric current and a magnetic field, which are amplified and sustained by the dynamo effect. Earth's magnetic field deflects most of the solar wind, whose charged particles would otherwise strip away the ozone layer that protects the Earth from harmful ultraviolet radiation. One stripping mechanism is for gas to be caught in bubbles of magnetic field, which are ripped off by solar winds. Calculations of the loss of carbon dioxide from the atmosphere of Mars, resulting from scavenging of ions by the solar wind, indicate that the dissipation of the magnetic field of Mars c…
