At PTB's campus in Braunschweig the Earth's magnetic field is measured continuously. The data are required for the compensation of the Earth's magnetic field when sensitive measuring tasks are carried out.
In a magnetically undisturbed area in the woods at PTB's site, the Earth's magnetic field can be measured in a small wooden hut with special magnetometers.
