The boundary is generally considered to be north of the Arctic Circle (66° 33’N), which is the limit of the midnight sun and the polar night. Other definitions are based on climate and ecology, such as the 10°C (50°F) July isotherm, which also roughly corresponds to the tree line in most of the Arctic.

Rough ground	The Pole The Magnetic North Pole lies at approximately 82.7 degrees North and 114.4 degrees West (2005), northwest of Canada's Sverdrup Island. However, this location is not fixed and is moving continually, even on a daily basis. The earth's magnetic pole is the focus of the planet's magnetic field and is the point that traditional magnetic compasses point toward. Each year the magnetic North Pole and the magnetic field shift, requiring those using magnetic compasses for navigation to be aware of the difference between magnetic north and true north. The magnetic pole was first determined in 1831, hundreds of miles from its present location.
