Research by Bangor University found that these birds, in this case, Eurasian reed warblers (Acrocephalus scirpaceus) use only the Earth's magnetic inclination and declination to determine their ...

Earth’s magnetic poles are constantly on the move, but they haven’t drifted far enough to actually flip in the modern age. Researchers know that Earth’s poles have flipped in the past ...

Likewise, a wire passing through a magnetic field creates an electric current within the wire. This is the basic principle that allows electric motors and generators to operate. In the Earth (see ...

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 ...

Magnetotactic bacteria synthesize magnetic iron nanominerals, which function as tiny compasses that allow the microbes to navigate using Earth's geomagnetic field. Earth's iron cycle is a very ...
