A compass orients along Earth's magnetic field lines The Earth's magnetic field has poles – north and south. These poles move , but are located relatively near the geographic north and south ...

Orienting means finding the cardinal directions. First, hold the compass flat, parallel to the ground at about belly-button ...

Imagine crossing vast oceans, soaring across continents, or tunneling deep beneath the earth—without ever getting lost. For some animals, this isn’t just a fantasy, but a daily reality. They possess ...

You start with a particle that has spin. A spinning particle is basically like a compass needle; it likes to point “north” along any magnetic field in the background. But there’s one big difference ...

So the team went to work turning some old rules of physics into a precision compass that uses magnetically sensitive atoms to make extremely accurate measurements of magnetic fields. The compass ...

In the experiment, the compass detected magnetic fields with a strength between 0.1 gauss, which is less than the Earth’s magnetic field, and 200 gauss, which is stronger than a small iron magnet.

We may have a clearer understanding of the physics that drive avian migration patterns.; Scientific American recently explained how birds use the Earth’s magnetic field to guide their migration ...

Dogs can typically smell and hear far better than their human companions. Now it appears they can sense Earth’s magnetic field too, say a team of biologists – and they show it when they poop.

Sharks Use the Earth’s Magnetic Field Like a Compass Biologists have long believed that these animals rely on magnetic sensing to migrate across oceans. Someone finally figured out how to prove it.

Monarch butterflies use a magnetic compass to migrate, researchers found. ... They could possibly have a map sense based on the magnetic field of the the Earth, Reppert said.
