Webinar: Understanding the magnetic field

Join us at a special webinar focusing on our our geomagnetism research, including how we measure the magnetic field, everyday applications and mitigating the threats of space weather.

Blog: Will 2024 be the Year of the Aurora?

The Sun's approximate eleven-year activity cycle is predicted to peak this year, prompting BGS scientists to anticipate that 2024 will be the 'Year of the Aurora'.

State of the Geomagnetic Field

A new report, authored by NOAA-NCEI and BGS, describes the performance of the World Magnetic Model (WMM) 2020 predictions against recent observations.

About BGS Geomagnetism

The Geomagnetism team measures, records, models and interprets variations in the Earth’s natural magnetic fields.

Our data and expertise help to develop scientific understanding of change in the Earth and the environment, from deep within the core out into space.

We also provide geomagnetic products and services to industry and to academic colleagues and we use our knowledge for information and education.
