<P> Earth 's magnetic field , is also known as the geomagnetic field , is the magnetic field that extends from the Earth 's interior out into space , where it meets the solar wind , a stream of charged particles emanating from the Sun . Its magnitude at the Earth 's surface ranges from 25 to 65 microteslas ( 0.25 to 0.65 gauss ) . Roughly speaking it is the field of a magnetic dipole currently tilted at an angle of about 11 degrees with respect to Earth 's rotational axis , as if there were a bar magnet placed at that angle at the center of the Earth . The North geomagnetic pole , located near Greenland in the northern hemisphere , is actually the south pole of the Earth 's magnetic field , and the South geomagnetic pole is the north pole . The magnetic field is generated by electric currents due to the motion of convection currents of molten iron in the Earth 's outer core driven by heat escaping from the core , a natural process called a geodynamo . </P>
