The North magnetic pole refers to the location in the Northern Hemisphere where the magnetic field is the strongest and compasses point towards it. Some synonyms for the North magnetic pole include the Arctic magnetic pole, the magnetic North, and the magnetic apex. It is important to note that the North magnetic pole is not the same location as the geographical North Pole, which refers to the point where the Earth's axis intersects its surface. The magnetic poles are constantly shifting and this phenomenon has been the focus of a lot of research, as it can affect navigation and communication systems.
