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.

Inclination, or dip angle, is the angle between the magnetic field and the surface of the Earth. Sure enough, he discovered that while birds usually arrive at the same site year after year ...

How some animals use the Earth’s magnetic field to navigate ... Determining latitude relative to an end point is more useful, and magnetic cues like intensity and inclination may help.

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 ...

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.

This article was originally published with the title “ Magnetic Sense Shows Many Animals the Way to Go ” in Scientific American Magazine Vol. 306 No. 1 (January 2012) doi:10.1038 ...

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 ...

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 ...

Current theories of geomagnetism state that the ‘dynamo’ that powers the Earth’s magnetic field is maintained by heat and gravitational energy. But previously observed long-term patterns in the ...
