The North Magnetic Pole moves over time due to magnetic changes in the Earth's core. Recently it was near Ellesmere Island in northern Canada and moving toward Russia at about 35 miles per year.
True North is exactly at the axis of the Earth's rotation. A magnetic compass reading (such as a Boy Scout compass) has to have a correction factor applied to get True North. This factor is called the magnetic declination and is different for every place on Earth and is constantly changing. The link below shows a map tracing the declination factors for most of the Earth as they are now.
In New York City Magnetic North is different from True North by about 14 degrees. Near the tip of the Florida panhandle Magnet and True north are the same -- that is, no correction is required.

True north refers to the geographic North Pole, the point at which the Earth's axis of rotation intersects its surface. Magnetic north, on the other hand, is the direction that a compass needle points towards, which is influenced by the Earth's magnetic field. The difference between the two is known as magnetic declination and varies based on location.

∙ 12y agoThe north pole of earth is geographic so it is right at the top of earth and the true magnetic north pole is the north part of the earth's axis.

What is the Is the difference between true North and magnetic north?
magnetic variation
True or false Declination is the difference between true north and magnetic north?
true
What is the name given to the difference between true north and magnetic north?
magnetic variation
What is the term used for difference between true north and magnetic north?
Magnetic declination or variation.
What is magnetic variation?
Since the Earth's magnetic poles are not located at the geographic poles, a magnetic compass doesn't point to 'true' (geographic) north. The DIFFERENCE angle between magnetic north and true north is the magnetic variation or declination where you are. It changes for different locations.
How is magnetic declination measured in the northern hemisphere?
It is measured exactly the same in the Southern hemisphere (no difference between the two hemispheres). It is the difference between magnetic north and true north and it varies all over the globe. Magnetic declination (also called magnetic variation) is positive when magnetic north is east of true north (clockwise) and it is negative when magnetic north is west of true north (anti-clockwise).
What is the difference between true north and magnatic north?
well one is that the true north is the north pole.And the magnetic north is the N on a magnet.
Why are there 2 norths magnetic north and the true north?
Magnetic north is the direction towards which a compass needle points, influenced by the Earth's magnetic field. True north, on the other hand, refers to the geographic North Pole, the point at which the Earth's rotational axis intersects its surface. The discrepancy between magnetic north and true north is known as magnetic declination and varies depending on the location on Earth.
What is the name of the difference of true north and magnetic north?
The difference is referred to as magnetic, or compass, declination.
What is the purpose of a declination?
Assuming the subject is magnetic declination the difference between the north pole and the true north pole this difference, is the magnetic declination, there is not information on what purpose it serves.
Why is it a problem to have a magnetic North Pole and a geographic North Pole?
An ordinary magnetic compass points to magnetic north, not to true north. If the difference between the two directions is large and not accounted for, you can get lost.
What is difference between true north and magnetic north in Cape Town South Africa?
25 degrees West
