Many non-magnetic materials possess the qualities of diamagnetism, such as water, wood, plants, animals, and human beings.

Millions of times weaker than a regular magnetic force, diamagnetism can cause levitation under the right circumstances.

Archaeomagnetic dating is the study and interpretation of the signatures of the Earth's magnetic field at past times recorded in archaeological materials.

These paleomagnetic signatures are fixed when ferromagnetic materials such as magnetite cool below the Curie point, freezing the magnetic moment of the material in the direction of the local magnetic field at that time.

After World War II, geologists developed the paleomagnetic dating technique to measure the movements of the magnetic north pole over geologic time. Robert Dubois introduced this new absolute dating technique to archaeology as archaeomagnetic dating.

Archaeomagnetic dating works because the earth’s magnetic field "wanders," continually changing its position in response to changes in the flow of liquid iron in the planet's core. As the clay cools, the alignment of the iron “fixes,” preserving a record of the magnetic field at a specific time in the past.

By tracking and cross-dating past changes in the location of the magnetic field, geophysicists have reconstructed a series of magnetic polar positions extending back more than 2,000 years. At archaeological sites, hearths constructed of iron-bearing clays are ideal for archaeolomagnetic sampling because they were subjected to repeated hot firings.

On the earth's surface, when you hold a compass and the needle points to north, it is actually pointing to magnetic north, not geographic (true) north.

The Earth's magnetic north pole can change in orientation (from north to south and south to north), and has many times over the millions of years that this planet has existed.
