What is 400 Years of Geomagnetic Change about?
The document discusses the geomagnetic evolution over 400 years, focusing on changes in the non-dipole geomagnetic field from 1600 to 2000 A.D. It highlights the dynamic nature of non-dipole foci, their lifetimes, and significant variations in spherical harmonic coefficients, particularly noting a change in the axisymmetric quadrupole around 1837 A.D. The findings are based on historical observations and analyses, culminating in a film that visually represents these geomagnetic changes.
