In fact, the magnetic pole is continually wandering around the geographic
pole. Maybe the fact that in some cases the geomagnetic field is
represented as a dipole, in first approximation, causes this kind of doubt.

The geomagnetic field is extremely complex, and is generated mainly in the
Earth's core, with some contributions from outside the Earth, what makes
the geomagnetic pole to move around in the neighborhood of the geographic pole.
