Figure 1: Magnetic field lines flow out of the South Magnetic Pole and reenter the globe at its northern end. Some creatures seem able to figure how steep the inclination angle of the field lines ...

Loggerhead turtles “dance” when exposed to food-associated magnetic fields, and their magnetic map may help them return to specific areas after long migrations.

Soprano pipistrelles can sense the polarity and inclination of magnetic field lines, and use the position of the setting sun to calibrate their internal compass By Richard Kemeny 29 May 2023 ...

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 ...

Earth’s magnetic field is generated by the spinning ball of molten iron at the planet’s center. It performs a variety of important functions, including acting as a shield against solar winds.

Another crucial component is magnetic inclination, which measures the angle between the magnetic field lines and the Earth’s surface. This inclination provides information about the latitude of ...

But how do birds sense magnetic inclination? “The answer is almost unbelievable,” says Wynn. There’s evidence that warblers can see the magnetic field. In birds’ eyes, a light-dependent ...

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 ...

Sometimes, the magnetic fields are relatively weak, like the ones that thread their way through the spiral arms of galaxies. Sometimes, they're medium-strength, like Earth's.

The universe is soaked in weak-but-persistent magnetic fields. Despite decades of research, astronomers still aren't exactly sure where these magnetic fields came from. But new research suggests ...

Earth’s magnetic field is detected by species across the animal kingdom, but new research suggests that sea turtles may be using it in a different way. February 12, 2025 3 min ...
