Definition of archaeomagnetism
- Archaeomagnetism (specifically, thermo-remanent magnetism) can also be used to date fired clay. Like [thermoluminescence], the principle is deceptively simple: the direction of the earth’s magnetic field has changed over time, and magnetic particles contained in clay align with the direction that prevailed at the time of their last intense heating (typically, firing in a kiln).
