The collection - Earth Magnetism

Some of the instruments presented here were used to measure the Earth magnetic field in the polar years 1932-1933 and the others were installed during the International Geophysics Year (1957-1958)  and still in use in French observatories in the southern hemisphere until 1980.

Here under is a brief view of some instruments of the collection. However, if you want to know how they work, just select them within the list on the left.
