The Geographic North Pole differs from the Magnetic North Pole by about 500 kilometers. The Geographic North Pole is where lines of longitudes converge into what we call the North Pole. The Magnetic Pole is a point in Northern Canada where the northern lines of attraction enter the Earth. A...

Earth’s magnetic north pole has shifted away from Canada and closer to Siberia at a rapid pace in recent years. Researchers believe two massive blobs of molten iron in Earth’s outer core may have spurred the runaway pole. There’s no telling where it will end up. The magnetic north...
when converting between magnetic and grid bearings. Differences between the three norths are given on our 1:50000 scale OS Landranger ® and OS Explorer 1:25000 maps. On OS Landranger Maps, the difference between True North and Grid North is given for each corner of the map and is ...
On a world map, these variations are usually indicated byisogonic lines. These are lines showing areas sharing the same magnetic declination. Without these variations, the magnetic declination on the meridian south of the magnetic North Pole would be 0 because both the magnetic and the geographical...

How to use magnetic declination to find true north? Map Reading and Magnetic North The majority of maps produced place true north at the top of the map this marks the Earth's axis of rotation. In addition the lines of longitude all converge at the north pole. Magnetic North, which is th...
