North Pole is northernmost part of the Earth & South Pole southernmost part of Earth.
Though it just the opposite in case of Magnetic North & South Pole.
Magnetic N-Pole is the Geographic S-pole of Earth & vice versa.

South Pole normally refers to the Geographic South Pole – the southernmost point on the surface of the Earth, on the opposite side of the Earth from the North Pole. Other "South Poles" described in this article include the Ceremonial South Pole, the South Magnetic and Geomagnetic Poles, and the Southern Pole of Inaccessibility.
Originally by analogy with the earth's magnetic field, the terms "south pole" and "north pole" are also applied to magnets in general, in order to distinguish one "end" of the magnet from the other. For this use see under Magnet and Magnetism.
North Pole usually refers to the Geographic North Pole – the northernmost point on the surface of the Earth, where the Earth's axis of rotation intersects the Earth's surface. Other "North Poles" described in this article include:
The North Magnetic Pole – the point on the Earth's surface where the Earth's magnetic field points directly downwards. This pole is constantly wandering; its estimated 2005 position was 82.7° N 114.4° W [1].
The North Geomagnetic Pole – the point of intersection of the Earth's surface with the axis of a simple magnetic dipole (like a bar magnet) that best approximates the Earth's actual more complex magnetic field. Like the North Magnetic Pole it constantly wanders; as of 2005 it was located at approximately 79.74° N 71.78° W [2].
The Northern Pole of Inaccessibility – the point in the Arctic Ocean farthest from land, at 84°03′N 174°51′W.
The North Celestial Pole – an imaginary point in the northern sky towards which the Earth's axis of rotation points.

Earth acts as an huge magnet ,as every magnet has both north and south pole were the magnetic field is maximum even earth is having its maximum magnetic field at its north and south poles.

The north and south pole are the two ends of a magnet which repel each other.The north pole will repel north pole and it will attract south pole.The south pole will repel south pole and it will attract north pole.for example , our earth is a goegraphical magnet.Its north pole is somewher near Canada and its south pole is towards antarctica.
The natural phenomonen of the northern lights (aurora boraelis) is due to earth's magnetic field.The compass , which is used for the navigation of the ships ,always points towards the north which is due to earth's magnetic field.

the north pole usually refers to the geographic north pole-the northernmost point of the surface of the earth,where the earths axis of rotation intersects the earth surface.south pole normally refers to the geographic south pole-the southernmost point on the surface of the earth,on the opposite side of the earth from the north pole.

North Pole
When not otherwise qualified, the term North Pole usually refers to the Geographic North Pole – the northernmost point on the surface of the Earth, where the Earth's axis of rotation intersects the Earth's surface. Other "North Poles" include:
* The North Magnetic Pole – the point on the Earth's surface where the Earth's magnetic field points directly downwards. This pole is constantly wandering; its estimated 2005 position was 82.7° N 114.4° W [1].
* The North Geomagnetic Pole – the point of intersection of the Earth's surface with the axis of a simple magnetic dipole (like a bar magnet) that best approximates the Earth's actual more complex magnetic field. Like the North Magnetic Pole it constantly wanders; as of 2005 it was located at approximately 79.74° N 71.78° W [2].
* The Northern Pole of Inaccessibility – the point in the Arctic Ocean farthest from land, at 84°03′N 174°51′W.
* The North Celestial Pole – an imaginary point in the northern sky towards which the Earth's axis of rotation points.
Originally by analogy with the earth's magnetic field, the terms "north pole" and "south pole" are also applied to magnets in general, in order to distinguish one "end" of the magnet from the other. For this use see under Magnet and Magnetism.
Precise definition
The Earth's axis of rotation – and hence the position of the North Pole – was commonly believed to be fixed until, in the 18th century, the mathematician Leonhard Euler predicted that the axis might "wobble" slightly. Around the beginning of the 20th century astronomers noticed a small apparent "variation of latitude", as determined for a fixed point on Earth from the observation of stars. Part of this variation could be attributed to a wandering of the Pole, by a range of a few meters. The wandering has several periodic components and an irregular component. The component with a period of about 435 days is identified with the 8 month wandering predicted by Euler and is now called the Chandler wobble after its discoverer. This "wobble" means that a definition of the Pole based on the axis of rotation is not useful when more than about 1'' precision is required.
South Pole
Amundsen-Scott South Pole Station. The ceremonial pole and flags can be seen in the background, slightly to the left of center, below the tracks behind the buildings. The actual geographic pole is a few more metres to the left. The buildings are raised on stilts to prevent snow buildup.

The Geographic South Pole
When not otherwise qualified, the term South Pole normally refers to the Geographic South Pole – the southernmost point on the surface of the Earth, on the opposite side of the Earth from the North Pole. Other "South Poles" described in this article include the Ceremonial South Pole, the South Magnetic and Geomagnetic Poles, and the Southern Pole of Inaccessibility.
Originally by analogy with the earth's magnetic field, the terms "south pole" and "north pole" are also applied to magnets in general, in order to distinguish one "end" of the magnet from the other. For this use see under Magnet and Magnetism.
Geographic South Pole
The Geographic South Pole is defined for most purposes as one of two points where the earth's axis of rotation intersects its surface (the other being the Geographic North Pole). However, the earth's axis of rotation is actually subject to very small "wobbles", so this definition is not adequate for very precise work; see Geographic North Pole for further information. The projection of the Geographic South Pole onto the celestial sphere gives the south celestial pole.
At present, Antarctica is located over the South Pole, although this has not been the case for all of Earth's history because of continental drift. The land (i.e. rock) at the South Pole lies near sea level, but the ice cap is 3000 meters thick so the surface is actually at high altitude.
The polar ice sheet is moving at a rate of roughly 10 meters per year, so the exact position of the Pole, relative to the ice surface and the buildings constructed on it, gradually shifts over time. The South Pole marker is repositioned each year to reflect this.
South Magnetic Pole
For additional information about the Earth's magnetic poles, see under North Pole.
The South Magnetic Pole is the point on the Earth's surface where the geomagnetic field lines are directed vertically upwards. The South Magnetic Pole is constantly wandering due to changes in the Earth's magnetic field; as of 2005 it was calculated to lie at 64.53°S and 137.86°E , just off the coast of Wilkes Land, Antarctica.
For historical reasons, the "end" of a magnet that points towards the Earth's North Pole is itself called the "north pole" of the magnet, with the other end being the magnet's "south pole". Because it is unlike poles that attract, the Earth's North Magnetic Pole is therefore actually a magnetic south pole, and the Earth's South Magnetic Pole is actually a magnetic north pole.
On January 16, 1909 three men (Douglas Mawson, Edgeworth David, and Alistair Mackay) from an expedition led by Sir Ernest Shackleton, claimed to have found the South Magnetic Pole , which was at that time located on land. However, there is now some doubt as to whether their location was correct .
South Geomagnetic Pole
The Earth's geomagnetic field can be approximated by a tilted dipole placed at the center of the Earth. The South Geomagnetic Pole is the point where the axis of this best-fitting tilted dipole intersects the Earth's surface in the southern hemisphere. As of 2005 it was calculated to be located at 79.74°S and 108.22°E , near to Vostok Station. Because the field is not an exact dipole, the South Geomagnetic Pole does not coincide with the South Magnetic Pole. Furthermore, the South Geomagnetic Pole is wandering for the same reason its magnetic counterpart wanders.
