Description:
These pages, authored and curated by David P. Stern, describe a dynamo process that creates the magnetic fields of the Earth and the Sun. Flows of electrically conducting material through existing magnetic fields produces electric currents, which maintain the magnetic field. Dynamos in the Earth's core reverse their north-south polarity, a process recorded by sea-floor magnetization, which confirms the slow motion of continents. Includes translations to Spanish, French and German.
