The video explains the concepts of magnetic, electric, and gravitational fields using simple demonstrations. It shows how iron filings reveal the magnetic field around a magnet, how charged objects ...

The ability to sense the Earth’s magnetic field—a trait known as magnetoreception—is well documented among many animals, but researchers have struggled to show that humans are also capable of the feat ...

Scientists have found that it’s possible to generate electric power from Earth’s rotation through its own magnetic field using a magnetic tube resting stationary on the planet’s surface. But before ...

When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. Imagine a bar magnet inside Earth, more or less aligned with the axis, where the ends of that ...

A compass needle is essentially a thin bar magnet. If it were free to move in all three dimensions, a magnet would line up along any local magnetic field line. Field lines are graphical ...

The northern lights arise when electrons from space cascade into the upper atmosphere, where they collide with oxygen and nitrogen molecules to paint the sky red and green (SN: 2/7/20). But it has ...

If you thought Jupiter's Great Red Spot was odd, wait until you get a look at its magnetic field. New data from Juno, a NASA space probe that's been orbiting Jupiter for the past two years, reveals ...

COME wintertime thousands of garden warblers, pied flycatchers, and bobolinks—all tiny songbirds—will cross the equator heading south for sunnier climes. It is an epic trip. For guidance they will ...
