Paleomagnetism decodes the history of Earth's magnetic field preserved in rocks. When volcanic lava cools or sediment settles, ferromagnetic minerals lock in the ambient field direction and strength like tiny compass needles frozen in stone. By measuring these fossil magnetizations, geophysicists reconstruct past pole positions, prove continental drift, date geomagnetic reversals, and constrain the dynamics of the outer core dynamo.
These simulations let you trigger geomagnetic polarity reversals, compute virtual geomagnetic poles from declination-inclination data, visualize the stereographic projection of field directions, trace apparent polar wander paths across geological time, and estimate paleointensity from Thellier-type experiments — all with interactive controls and scientifically accurate models.
