Magnetic field of the earth
View the video of the magnetic fields of the earth.
It is interesting to note that the magnetic field of the Earth is roughly
the shape of the magnetic field of a bar magnet, with its axis slightly
inclined to the axis of rotation of the Earth. Since the N end of a compass
needle points to geographic north, there must be a magnetic south pole in
this region. Similarly, there is a magnetic north pole at the geographic
south pole. The magnetic field strength near the surface of the Earth is
approximately 10 tesla.
