paleomagnetic /pay'lee oh mag net"ik/ or, esp. Brit., /pal'ee-/, adj.
/pay'lee oh mag"ni tiz'euhm/ or, esp. Brit., /pal'ee-/, n.

or palaeomagnetism or remanent magnetism

Permanent magnetism in rocks, resulting from the orientation of the Earth's magnetic field at the time of rock formation in a past geologic age.

It is a source of information for the paleomagnetic studies of polar wandering and plate tectonics.
