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.

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 ...

Monarch butterflies use Earth’s magnetic field as a compass. Cold winter temperatures reverse their direction for spring ...

Bogong moths navigate to alpine caves by using a stars and Earth's magnetic field. They can change direction based on star ...

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 ...

The compass run indicates that dogs are feeling the pull of the magnetic field, even if they only use it to set the stage before they start to track a scent.

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