Once you have your declination, adjust your compass with your fingers or a tool ... Turn your body (not just the compass) so ...

THE Meteorologische Zeitschrift for April contains an interesting article by Prof. G. Hellmann on the knowledge of the magnetic declination before the time of Christopher Columbus. Some years ago ...

With the right preparations and technological solutions in place, aviation would continue to operate safely, even during a magnetic pole reversal.

Pilots and mariners rely on updated magnetic declination values to correct their compass readings. The World Magnetic Model, updated every five years, provides essential data for these corrections.

New research uncovers how birds navigate using Earth's magnetic inclination and declination, redefining migration science.

The research provided strong evidence that migratory birds rely on inclination and declination to determine their location, even when these cues conflict with other magnetic field components.

Migratory birds rely on Earth’s magnetic inclination and declination for navigation, not total intensity. This reveals a flexible and precise internal mapping system. Migratory birds can navigate ...

Many migratory birds use Earth’s magnetic field as a compass, but some can also use information from that field to determine more or less where they are on a mental map. Eurasian reed warblers ...

Magnetic declination varies from place to place due to the changing nature of the Earth's core. To compensate, many allow you to adjust your compass readings to accommodate the magnetic ...
