This allows us to predict the direction of the magnetic field at any location on Earth’s surface using the fundamental equations of a dipole field.This equation gives a direct relation between magnetic inclination and geographic latitude at the point of observation. a magnetic compass which points north will now point south and vice versa) and these reversals are symmetrical (i.e.the normal and reversed field directions are exactly anti-parallel).The above is the fundamental assumption used to reconstruct continents to their past positions using the ancient magnetic field recorded in rocks (fossil magnetism).

And as paleomagnetists gather more information, we can continue to learn more about the planet’s history.Scientists can study the history of Earth’s magnetic field by using Earth’s rocks as records.Paleomagnetism is the study of magnetic rocks and sediments to record the history of the magnetic field.A more detailed record of Earth’s magnetic past will provide answers regarding the formation of the continents as well as the behavior of our magnetic field.In this article we shall discuss how we can use the paleomagnetism in rocks to attach dates to them (paleomagnetic dating).
