The North Magnetic Pole is the point on the Earth’s surface where the Earth’s magnetic field points vertically downward. It is located in the Arctic Ocean, north of Canada and west of Greenland. The North Magnetic Pole is not the same as the geographic North Pole, which is located at the northernmost point on the Earth’s surface.
The North Magnetic Pole moves over time due to the Earth’s magnetic field, which is constantly changing. The current location of the North Magnetic Pole is approximately 85.9°N, 121.2°W.
What is the Earth’s Magnetic Field?
The Earth’s magnetic field is a region of space around the Earth where charged particles are influenced by the Earth’s magnetic field. The magnetic field is created by the movement of the Earth’s liquid outer core.
The Earth’s magnetic field is not static, but is constantly changing. The North Magnetic Pole has been moving slowly but steadily northward for centuries.
How is the North Magnetic Pole Used?
The North Magnetic Pole is used for navigation. Compasses align themselves with the Earth’s magnetic field, pointing towards the North Magnetic Pole. This allows sailors and other navigators to find their bearings.

Magnetism in the Earth
Earth’s magnetism arises from the movement of molten iron in the planet’s outer core, creating a magnetic field that surrounds the planet. This field extends into space and protects the Earth from harmful solar radiation. The Earth’s magnetic field is constantly shifting, causing the magnetic poles to change location over time.
The magnetic field provides navigational guidance to animals, including humans. It also creates the aurora borealis and aurora australis, the stunning light displays seen in polar regions. Understanding Earth’s magnetism is crucial for studying planetary dynamics, protecting against geomagnetic storms, and advancing technologies that rely on magnetic field measurements.
Where is the North Magnetic Pole of Earth in Russia?
The North Magnetic Pole is the point on the Earth’s surface where the magnetic field lines point vertically downward. It is not fixed but moves over time due to changes in the Earth’s magnetic field. As of 2023, the North Magnetic Pole is located in northern Siberia, Russia, about 1000 kilometers (620 miles) from the geographic North Pole. It is constantly moving northwestward, and its precise location is regularly updated by the World Magnetic Model.
Geographical Poles of Earth
The geographical poles of the Earth are its two rotational axes, which intersect the Earth’s surface at the North Pole and the South Pole. These points are the extreme north and south ends of the globe and mark the areas where the Earth’s axis intersects its surface. The geographical poles are not the same as the magnetic poles, which are the points on the Earth’s surface where the magnetic field lines emerge or converge.
Earth’s Magnetic Field
The Earth’s magnetic field is an invisible force field that surrounds the planet. It is generated by the movement of molten iron in the Earth’s outer core. The magnetic field protects the Earth from harmful solar radiation and cosmic rays by deflecting them away from the planet. It also helps to orient animals and birds during migration. The magnetic field is not static, but rather changes over time. These changes can be caused by a variety of factors, including the movement of the Earth’s core and the solar wind.
