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 ...

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.

Great white shark researcher Salvador Jorgensen of the Monterey Bay Aquarium says he thinks the finding that sharks use Earth’s magnetic fields to orient and navigate is likely to apply to a ...

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 ...

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