As the earth rotates, these electric currents produce a magnetic field that extends outward into space.This process, in which the rotation of a planet with an iron core produces a magnetic field, is called a dynamo effect.

I hope these jokes make you laugh, happy and free from stress!It is no doubt that even the earliest coastal maps must have alluded to the similarities between coastlines.

Ideas of paleomagnetism began in the late 1920s, when French physicist Mercanton, suggested that because today's magnetic field is close to the earth's rotational axis, continental driftcontinental drift,geological theory that the relative positions of the continents on the earth's surface have changed considerably through geologic time.

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.

It also has the useful property of pointing roughly North (or South).

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.

The study of paleomagnetism has demonstrated that the Earth's magnetic field varies substantially in both orientation and intensity through time.
