the earth has a magnetic field that is essentially anchored by two poles -- magnetic north and magnetic south. A compass uses a magnetized needle that is constantly drawn to magnetic north.

Explorers have long trusted compasses to navigate Earth's land and oceans, using our planet's global magnetic field as their guide. But what happens when you take a compass beyond Earth - into ...

Would a dramatic change in the Earth's magnetic field affect creatures that rely ... So they can sense it, but can they use it like we do a compass, to orient themselves? In another experiment ...

A magnetic field is invisible, but it can be detected using a magnetic compass. A compass contains a small bar magnet on a pivot so that it can rotate. The compass needle points in the direction ...

With today’s data rates of only a few hundred megabytes per second, access to digital information remains relatively slow.

are known to navigate using the magnetic field lines that stretch from Earth's North to South Pole. Scientists knew the ...

Precisely how such species navigate remains undetermined, but growing evidence suggests the animals use the magnetic field of the Earth as a map and compass. To determine whether turtles can learn ...

The turtles rely on Earth’s magnetic field to help them navigate in two ways. A magnetic map aids with location tracking, and a magnetic compass orients them in the right direction. Now ...

Explorers have long trusted compasses to navigate Earth’s land and oceans, using our planet’s global magnetic field as their guide. But what happens when you take a compass beyond Earth — into orbit, ...

One theory is that some can detect the magnetic field's influence during a chemical ... that "a reasonable working hypothesis is that the compass sense relies on chemical magnetoreception, whereas ...
