Contents Notes
The Geomagnetic Field -- The Recent Geomagnetic Field and its Variations -- Records of Paleomagnetic Field Variations -- Numerical Models of the Geodynamo: From Fundamental Cartesian Models to 3D Simulations of Field Reversals -- Effects of Geomagnetic Variations on System Earth. Earth's magnetic field is currently changing dramatically. Is the observed decrease of the dipole moment indicating a future polarity transition? What would be the effects of such a drastic change on system Earth? Can any positive or negative effects on our biosphere or even humans be expected? This book gives a first overview about the geomagnetic field in general and serves as an introduction into geomagnetism. As the topic of the book covers a wide range of scientific disciplines, the first chapter summarises basic principles of geomagnetism and related fields including a historic overview, instruments and measurements, paleomagnetic fields, basics of dynamo theory, etc. The contributed chapters review major results of international activities aiming at understanding the causes and effects of geomagnetic field variations in view of the questions above.
