Geomagnetism is a science area within Earth Hazards and Systems, a programme of the British Geological Survey (BGS). BGS is a component body of the Natural Environment Research Council.

The main function of the geomagnetism team is to monitor the earth's magnetic field in the United Kingdom. This work involves the continuous operation of three observatories and regular occupation of repeat stations in the UK.

Additionally, contributions are made to the international effort of global monitoring of the magnetic field by the operation of four observatories overseas.

Geomagnetism staff have expertise in the production of local and global models of the field and analyses and interpretations of geomagnetic data in real-time to serve both the academic and commercial communities.
