Most people have a rough idea of the cause of Earth's magnetic field, don't they? It's the geodynamo, also called the magnetic dynamo theory. The heat from the solid inner core puts the liquid outer core in motion, and the movements of the outer core's electrically conducting fluids (such as molten iron) generate the planet's magnetic field. Electrically conducting fluids occur in the Sun, other stars and most planets – and are the scientifically accepted mechanism for magnetic fields. However, the planet Mercury suggests this process is wrong. Is it possible to propose a plausible alternative? The proposal here has both Earthly and Space components - it is still linked to the nature of, and motions in, the core plus it refers to the phenomenon of zero electrical resistance known as superconductivity as well as the recent discovery of gravitational waves. It also refers to the Moon's attraction on Earth's oceans, binary stars, the Sun's coronal heating and mass ejections, sunspots and mini ice ages, and black holes. A proposal that has support from only one or two sources may indeed prove to be correct. But surely support from several additional sources must greatly improve that proposal's chances of success. It's the goal of this article to be comprehensive in presenting its approach to the geodynamo. It's important to properly understand our planet's magnetic field because it protects us from the charged particles of the solar wind and cosmic rays. Without this protection from the magnetosphere, Earth would be stripped of its ozone layer that keeps excess ultraviolet radiation from harming life. And no magnetic field also means no atmospheric light displays called auroras, as well as no direction-finding compasses.
