For decades, scientists have speculated that sharks must be using the Earth’s magnetic field as a sort of atlas, but it was hard to prove because sharks are notoriously difficult to study.

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.

Dogs are probably using Earth’s magnetic field to navigate and roam around, a new study finds. They fit hunting dogs with GPS trackers and cameras and found they often returned home using an ...

Compass for magnetic field measurement "Until now, there have only been theoretical considerations on how the direction of a magnetic field can be determined with a scalar magnetometer," says ...

The field also can provide a compass direction; the declination of a compass indicates deviation from the North Pole/South Pole axis of rotation of the earth (related, roughly, to longitude, and ...

For 20 years, experts hypothesized that this protein served as birds’ magnetic sensor, a microscopic compass that points the bird in a particular direction.

“With our device, we now have a kind of compass for measuring the magnetic field, which shows us the strength and direction.
