Discovery, description and interpretation of Earth´s magnetic field in human history
Properties, observation and description of the modern geomagnetic field
Spherical harmonic geomagnetic field analysis - internal and external sources
Exercises in measuring and calculating the local elements of the geomagnetic field
Physics, history and reconstruction of geomagnetic (paleo-)secular variation
Discovery, history and statistics of past geomagnetic field reversals
Practical exercises in magnetostratigraphic dating
Physical principles of and geological preconditions for the geodynamo
Analog and numerical geodynamo models: controlling factors, results and limitations
Introduction to solar physics and historical heliomagnetic field behavior
Structures, processes, exploration and relevance of the Earth´s magnetosphere and ionosphere

- understand the complex physical conditions and processes from the core to the magnetosphere and solar system that generate and permanently vary the geomagnetic field
- measure and calculate main field geometry, perform magnetostratigraphic dating, and analyze geodynamo model results and short-term field variations
