A compass does not point directly at the physical location of magnetic north. It is oriented along the Earth's magnetic field lines at its location.

A compass does not point directly at the physical location of magnetic north. It is oriented along the Earth's magnetic field lines at its location.

The result that magnetic-field detection might have evolved separately for the map and compass senses bolsters growing evidence for dual magnetoreception systems in other vertebrates 1, 3.

Using this method, [efeyenice983] found that the Earth’s magnetic field strength at their location was about 0.49 Gauss, which is well within 0.25 to 0.65 Gauss that is typically found on the ...

New research hints at the biophysical underpinnings of their ability to use Earth’s magnetic field lines to find their way to their breeding and wintering grounds ...

Sushkov’s experiments use the spins of atoms as miniature compass needles that can sense other quantum particles through their magnetic influence. Researchers have long leveraged this phenomenon, ...

Most of the factors proposed can be essentially excluded, such as difficulties to extract magnetic compass information at high latitudes, methodological or experimenter biases, holding duration and ...

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.

Migratory bats use a magnetic sense to navigate long distances, calibrating their internal compass based on the position of the setting sun each evening. Many animals may use Earth’s magnetic ...
