Earth is surrounded by a magnetic field generated by electric currents from within the planet. Compasses take advantage of this field to identify north and serve as a navigational aid. But one social ...

Some inventions are so simple that it’s hard to improve them. The magnetic compass is a great example — a magnetized needle, a bit of cork, and a bowl of water are all you need to start navigating the ...

“Migratory birds possess a true magnetic compass—they can actively sense and extract directional information from the Earth’s ...

Just as the ancient Minoans of Crete used the stars for maritime navigation, birds today migrate with the help of Earth’s magnetic field. ⇨ Love animals and science as much as we do? Join Pop Mech Pro ...

We tend to think of Earth as a well-documented planet. We've mapped its continents, sampled its oceans, drilled into its ...

Atomic physicists “are jacks of all trades,” according to Alex Sushkov. “You have to have the idea, design the experiment, build the experiment, run the experiment, fix everything, take data, analyze ...

Earth's magnetic field does more than keep everyone's compass needles pointed in the same direction. It also helps preserve Earth's sliver of life-sustaining atmosphere by deflecting high energy ...

Nocturnal insects may use both the Earth’s magnetic field and visual cues to guide their migratory flight behaviours, according to recent findings. The research, published in eLife as a Reviewed ...

Research BackgroundWhen walking through a dense forest, a compass is indispensable for knowing which direction to take, and it works because the Earth ...
