Pole of the earth.

Do you know?

Earth

1.Magnetic south pole of the earth.

2.Geographical north pole of the earth.

  The earth behaves as a magnet. Hence it must also have north and south poles. However the geographical North and South poles as well as  magnetic north and south poles are not at the same place. In 1832 it was discovered that the earth’s magnetic south pole was situated over the north of  Hudson Bay in Canada. Magnetic North pole is situated to the south of Australia. Therefore the axis of rotation of the earth and the axis through the magnetic poles of the earth are not the same.
