Romania geomagnetic map


from 01/06/2019 until 20/12/2025

The geomagnetic map of Romania is a citizen science project, open for contribution to all citizens. Any person can contribute to the data collection, so that, through the contribution of several people, a realistic map of the values ​​of the magnetic field in various locations of Romania can be built. Participants only need 10 free minutes and a smart phone. Detailed instructions are available, including pictures. The data are collected by the European Researchers' Night team, and the resulting map is updated regularly. The map is presented and discussed for the public at large on the last day of September, each year, as part of the Researchers' Night event.


Why the geomagnetic map? Planet Earth is a huge magnet. A geomagnetic map shows us how the values ​​of the Earth's magnetic field are distributed, depending on the geographical position. If we collect enough data from different places, we can make comparisons and we can observe high or low values, called geomagnetic anomalies, related for example to rock magnetism.

Needed equipment

Smart phone equipped with any magnetometer type. Recommended App to find the magnetometer readings: Physics Toolbox Sensor Suite.
