There, they placed the birds temporarily in outdoor aviaries, where the researchers used a Helmholtz coil to interfere with magnetic fields. They artificially altered the inclination and ...

young loggerhead sea turtles can detect not only the field's intensity but its inclination, the angle at which magnetic field lines intersect the Earth. The turtles use these two pieces of ...

The research provided strong evidence that migratory birds rely on inclination and declination to determine their location, ...

the study team examined the two key features of Earth’s magnetic field: inclination, or the tilt of magnetic field lines relative to Earth’s surface, and intensity, or the strength of the ...
