Geophysical research Geomagnetism Space plasma physics Aeronomy Planetary research Auroras Research on geomagnetism at GEO has its roots in the early history of FMI in 1830's when the Helsinki magnetic-meteorological observatory was founded. Together with the expansion of GEO to space research, the magnetism group is closely involved both with near earth plasma studies as well as with planetary research .
Geomagnetic charts are one of the most important products of the magnetism group.
Geomagnetic induction occurs due to the interaction between ionospheric currents and conducting earth.
