The statement you're referring to is a misconception likely based on the following:
* Magnetic Poles: The Earth's magnetic field is not perfectly aligned with its rotational axis. This means the magnetic North Pole and magnetic South Pole are not exactly at the geographic poles. These poles are constantly moving and are not fixed points.
* Geomagnetic Poles: In addition to the magnetic poles, there are also geomagnetic poles, which are points where the Earth's magnetic field lines are perpendicular to the Earth's surface. There are actually two geomagnetic poles in each hemisphere, a north geomagnetic pole and a south geomagnetic pole.
However, it is crucial to remember that these additional poles are not the same as the true North and South Poles. The geographic North Pole and geographic South Pole are fixed points on the Earth's axis of rotation.
