What is Archaeomagnetism?
Archaeomagnetism
By comparing the magnetic direction recorded by the feature with a calibrated reconstruction of changes in the magnetic field through time, we can determine when that feature acquired the measured direction.

Field Forms and Tips
Archaeomagnetism refers to the application of paleomagnetic methods and theory to archaeological problems. Usually, the term refers to archaeomagnetic dating. This chronometric technique is based on two fundamental principles:

1. Many archaeological features contain magnetic minerals that will record the direction and strength of the Earth’s magnetic field under certain conditions.

2. The direction and strength of the Earth’s magnetic field changes through time, with significant changes occurring on the order of centuries.
