Head of division: Nils Olsen
 
The Division of Geomagnetism uses magnetic field measurements from satellites and ground stations to explore the Earth.

The magnetic field provides valuable knowledge about Earth's interior, because its slow variations reflect movements of the material in the core, rapid field changes depend on the electrical conductivity of the upper mantle, and because small wavelengths features can be used to map crustal structures. The magnetic field can also be used to explore the upper atmosphere (ionosphere and magnetosphere) and its connection with processes on the Sun.

 

The division’s activities primarily focus on:

  • measuring Earth's magnetic field
  • investigating the underlying physical processes producing the field and its variations
  • developing methods to separate the different contributions from the core, crust and the Earth's upper atmosphere (ionosphere and magnetosphere)
  • developing and calibrating instruments to measure the Earth's magnetic field, which are used in observatories around the world.
