 The Earth's magnetic north pole is drifting from northern Canada towards Siberia with a presently accelerating rate— per year at the beginning of the 20th century, up to per year in 2003, and since then has only accelerated.The Earth's magnetic field is believed to be generated by electric currents in the conductive iron alloys of its core, created by convection currents due to heat escaping from the core.However the process is complex, and computer models that reproduce some of its features have only been developed in the last few decades.
