INTRODUCTION
Earth’s magnetic field, is also known as the geometric field, is the
magnetic field that extends from earth’s exterior to where it meets
a solar wind, a stream of charged particle emanating from the sun.
It’s magnitude at the earth’s surface is Earth's magnetic field, also
known as the geomagnetic field, is the magnetic field that extends
from the Earth's interior to where 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 10 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. Unlike a bar magnet,
however, Earth's magnetic field changes over time because it is
generated by a geodynamic (in Earth's case, the motion of molten
iron alloys in its outer core). The North and South magnetic poles
wander widely, but sufficiently slowly for ordinary compasses to
remain useful for navigation. However, at irregular intervals
averaging several hundred thousand years, the Earth's field
