If you need help visualizing magnetic fields, these slow-motion video captures should educate or captivate you. Flux lines are difficult to describe in words, because magnet shape and strength ...

The needle is being affected by the Earth’s magnetic field. One end points towards magnetic north and the other end points south. You can use a compass to check which direction each end is facing.

A new video shows how Earth's magnetic field weakened and warped before temporarily flipping during a recent "polar reversal event." When you purchase through links on our site, we may earn an ...

Accompanying those electrical signals are tiny magnetic fields that have only recently been tapped for information into how the human body works. “Our natural magnetic fields offer a different ...

When an electric current passes through a metal wire, a magnetic field forms around that wire (see diagram at right). Likewise, a wire passing through a magnetic field creates an electric current ...

By studying robins, scientists have found clues to how birds sense the Earth's magnetic field. Just as you might reach for a magnetic compass to find which way is north or south, birds are thought ...

David Bressan is a geologist who covers curiosities about Earth. Without its magnetic field, life on Earth would not be possible since this shields us from harmful cosmic radiation and charged ...

Earth's magnetic field dramatically flipped a little more than 40,000 years ago. We can now experience this upheaval as an unnerving clatter interpreted from information collected by the European ...

It’s something [mircemk] demonstrates, with an Arduino-powered magnetic field strength meter that uses a UGN 3503U Hall effect device. The circuit is extremely simple, comprising the sensor ...

In the realm of electronics, scientists can control the movement of electrons using magnetic fields. The Lorentz force, ...
