Magnetic declination or variation.
The term for the attraction or repulsion between the poles of magnets is called magnetic force. This force is a result of the magnetic field that surrounds magnets and interacts with other magnetic materials.
The term for the apparent tendency of the north magnetic pole to vary in position over time is magnetic pole drift or magnetic pole wander.
'Magnetic North' is the name given to a location in the Arctic, to differentiate it from 'True North'. Whereas True North is fixed and located at the Earth's axis of rotation, the 'Magnetic North' varies from year to year. The term, 'Magnetic North', does not describe the magnetic polarity at that location which, actually, is a south pole.
magnetic force
magnetic south pole is closer to the geographic north pole..... that's why north pole of bar magnet when suspended free in air shows the north direction...
You must not confuse 'Magnetic North' with 'north magnetic pole', as these two things are completely different! 'Magnetic North' is a location, while 'north magnetic pole' refers to the magnetic polarity of the earth's 'Magnetic South'.'Magnetic North' is the point on the earth towards which magnetic compasses point. It is not a fixed position. It is presently (2012) in Canada and is drifting toward Siberia. It should not be confused with Grid, Geographic, or True North, which is a fixed point located at the axis about which the earth revolves. The same applies to the Magnetic South.The term, 'Magnetic North' describes a location, and has absolutely nothing to do with its magnetic polarity. The magnetic polarity of the location we call Magnetic North is actually a south pole, which is the reason it attracts the north pole of a magnet or compass needle.
They both refer to the same thing. Sedan is a North American term and Saloon is a British term.
actually the north pole of our earth(considering it as a big bar magnet) is the geographic south pole.Its called so because it lies on the northern hemisphere.Actually it is the south pole of our big bar magnetAdditional AnswerThe north magnetic pole of a compass needle points to Magnetic North. "Magnetic North" is so-called to differentiate it from "True North", and has nothing whatsoever to do with its magnetic polarity. Actually, the magnetic polarity of Magnetic North is a south pole which, because unlike poles attract, attracts the north pole of the compass needle.
The term for the attraction or repulsion between magnets is called magnetic force. This force is a result of the magnetic fields produced by the magnets interacting with each other.
The line with which a compass aligns is called "magnetic north." This term refers to the direction that a compass points, which is toward the Earth's magnetic north pole. Unlike true north, which is the geographic North Pole, magnetic north can vary based on geographic location due to the Earth's magnetic field fluctuations. This alignment helps navigators determine direction and orientation.
The term "North Pole" is a misnomer because it can refer to two distinct locations: the geographic North Pole, which is the point where the Earth's axis of rotation meets its surface at 90 degrees north latitude, and the magnetic North Pole, which is the point where Earth's magnetic field points vertically downwards. The magnetic North Pole is constantly shifting due to changes in Earth's magnetic field. Additionally, the North Pole is often thought of as a landmass, but it is actually located in the Arctic Ocean, covered by shifting sea ice.
It aligns with the Earth Magnetic field. The Earth is a huge dynamo. Its center made of nickel is surrounded by molten iron and other metals this generates a complex magnetic field. It meanders. That is it varies in location. You can find a map of its' previous locations.Alternative AnswerAs the previous answer says, a compass needle will align itself with the earth's magnetic field, thus indicating 'Magnetic North'. The term 'Magnetic North' is used to differentiate this direction from 'True North', and navigators must know where Magnetic North is, relative to True North, to accurately plot a course.Bear in mind, however, that 'Magnetic North' is a direction, and NOT a magnetic polarity. The magnetic polarity of Magnetic North is actually a south pole and, since 'unlike poles attract', it attracts the north (-seeking) end of the compass needle.
