The research team has identified atacamite as a material with magnetocaloric properties. Natural crystals have long ...
An Australian moth follows the stars during its yearly migration, using the night sky as a guiding compass, according to a new study.
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 ...
From the divine to the craptacular. Literally.And, like water and oxygen, lifeforms on Earth have evolved to make use of this resource. We may need to take a compass with us on low-tech hikes ...
For individuals using a compass, it means that the direction indicated by the compass needle can change over time. This can lead to navigation errors if the magnetic declination is not accounted for.
Migratory birds can extract positional information from magnetic inclination and magnetic declination alone. Proceedings of the Royal Society B: Biological Sciences, 2024; 291 (2034) DOI: 10.1098 ...

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 ...
Scientists have long believed that these birds use a 'map-and-compass' system: they first determine their location using a 'map' and then use a 'compass' to orient themselves in the correct direction.
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 ...
If magnetic north lies directly between you and true north, then you’ll have a declination of zero. But in most areas, you’ll have to add or subtract to what your compass reads as north.
