Earth's magnetic field
The areas in between the north and south magnetic poles are the magnetic field lines. These lines leave the Earth from the vertical point of the South and reenters through the vertical point of the North. These two vertical points are called magnetic dip poles. The magnetic dip poles are commonly referred to as the magnetic poles.  The magnetic poles intersect the earth at two points.  The north magnetic pole intersects the Earth at 78.3 N latitude and 100 W longitude.  This places the north magnetic pole in the Arctic Circle.  The south magnetic pole intersects the Earth at 78.3 S latitude and 142 E longitude.  This places the south magnetic pole in Antarctica.  The magnetic poles are also where the magnetic fields are the strongest.
