Angles and Directions

Magnetic Declination

Description

Magnetic declination is the angle between true north, which aligns with the Earth's rotational axis, and magnetic north, which follows the direction of the Earth's magnetic field. This discrepancy exists because the magnetic poles do not coincide with the geographic poles. The value of magnetic declination depends on the observe...

Transcript

Magnetic declination is the angle between true north or astronomic north and magnetic north. This angle arises because Earth's magnetic poles do not align with its geographic poles. 

The magnetic declination varies by location and changes over time due to shifts in Earth's magnet...
