Dec 28, 2010· The copper slag contained tiny iron inclusions that recorded the strength of the geomagnetic field at the time it cooled and solidified. Wired Science reported, "They found that the magnetic field abruptly spiked twice during the 180 years they studied, once around 2,990 years ago and once around 2,900 years ago." 3

The strength of the magnetic field it produces is at any given point proportional to the magnitude of its magnetic moment. In addition, when the magnet is put into an external magnetic field, produced by a different source, it is subject to a torque tending to orient the magnetic moment parallel to the field.

Earth's magnetic field, also known as the geomagnetic field, is the magnetic field that extends from the Earth's interior out into space, where it interacts with the solar wind, a stream of charged particles emanating from the magnetic field is generated by electric currents due to the motion of convection currents of molten iron in the Earth's outer core: these convection currents are ...
