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 ...
How does a compass work in space? From the moon to Venus, here's how a compass would work beyond Earth's magnetic field.
On Earth, the magnetic field of our planet points a compass north, but in space, things are a bit more complicated. When you purchase through links on our site, we may earn an affiliate commission ...
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 ...
Every year, billions of birds migrate in and out of the United States. And across the world, birds fly thousands of miles to reach their seasonal destinations. Some birds, like the Arctic tern ( ...
If the magnetic field is going through the rotor in the wrong direction relative to the brushes you generate no current. Like if you were to install magnets in a generator 90 degrees out of phase ...
Researchers have discovered why atacamite, a rare mineral found in Chile, spontaneously cools down when exposed to a magnetic ...
Deep in Chile’s Atacama Desert, scientists studied a green crystal called atacamite—and discovered it can cool itself ...
Many migratory birds use Earth’s magnetic field as a compass, but some can also use information from that field to determine more or less where they are on a mental map.
Earth's magnetic field may influence the spin of these free electrons, which birds could then detect, explains biophysicist Thorsten Ritz of the University of California at Irvine, ... with birds ...
Loggerhead turtles “dance” when exposed to food-associated magnetic fields, and their magnetic map may help them return to specific areas after long migrations.
