1. Geomagnetic Poles

   Linked via "geomagnetic coordinate system"

   Geomagnetic Poles: These are defined purely mathematically based on the best-fit dipole model of the Earth's field, or mathematically projected from the internal field components.
   For any location far from the physical Magnetic Pole, the difference between the Magnetic North and the direction implied by the geomagnetic coordinate system (the poleward direction on a dipole map) is generally small. However, ne…
