The Earth magnetic field is a dating tool

Dr Agathe Lise-pronovost

The Earth magnetic field mostly behaves like a giant bar magnet; however, we know from 400 years of compass and satellite measurements that outstanding changes occur at the human timescale. The history of these changes back in time can be recovered from rocks and sediments at the Earth surface and used as a dating tool for archaeology and paleosciences.
