Agonic line

The Agonic line is an imaginary line that runs across the surface of the Earth, where the magnetic and geographic poles align. Along this line, there is no magnetic variation, which means that the magnetic needle on a compass will point towards true north. This line is irregular in shape and location and can shift over time due to changes in the Earth’s magnetic field. The Agonic line is an important reference for navigation and mapping, as it helps in determining the magnetic declination at a particular location. It is essential for pilots, navigators, and surveyors to have accurate information about the Agonic line to avoid errors in their calculations. In recent years, the location of the Agonic line has been shifting more quickly than before due to changes in the Earth’s magnetic field. Understanding the Agonic line is crucial for anyone who needs to navigate accurately across the Earth’s surface.
