In 1831, James Clark Ross located the north dip pole position in northern Canada. Natural Resources Canada (NRCan) tracked the North Magnetic Pole, which is slowly drifting across the Canadian Arctic, by periodically carrying out magnetic surveys to reestablish the Pole's location from 1948 to 1994.
The north pole is moving at a dangerous pace - Earth.com
The magnetic north pole is currently en route to Siberia, moving eastward at about 40 kilometres per year which could disrupt technology.
North magnetic pole - Wikipedia
The geomagnetic north pole is the northern antipodal pole of an ideal dipole model of the Earth's magnetic field, which is the most closely fitting model of Earth's actual magnetic field. The north magnetic pole moves over time according to magnetic changes and flux lobe elongation [2] in the Earth's outer core. [3]

Polar wandering | Definition & Facts | Britannica
polar wandering, the migration of the magnetic poles over Earth ’s surface through geologic time. The study of polar wandering began in the early 20th century with Austrian priest and geologist Damian Kreichgauer and German scientists Wladimir Köppen and Alfred Wegener, who proposed the first paths of geomagnetic North Pole migration.
