North pole vs magnetic North pole vs geomagnetic North pole
In: Physics
North pole = the axis the earth rotates on (north end)
Geomagnetic north pole = location of the north pole of the earths magnetic field
This pole is different than the rotational axis. Its also constantly moving. Land nav maps will include the angle difference of magnetic north from true north (called the declination).
Last time I reference the magnetic north pole was somewhere in Canada with a general heading going northeast towards Russia. It is not a straight line path.
Magnetic North Pole = the north pole of a magnet
