A rare geological event occurs every 300,000 years or so: the Earth’s magnetic poles flip. The magnetic poles are the two ...

The updated version of the World Magnetic Model was released on Dec. 17, with a new prediction of how the magnetic north pole ...

One way to get moving charges is to run electric current through a wire. (This is literally a stream of electrons.) This will create a magnetic field, and other wires with electric current will ...

As you may recall from Physics 101, a changing magnetic field (like when you slide a bar magnet through a copper coil) induces an electric current. At planetary scale, Earth’s magnetic field induces ...

The impacts of space weather such as extreme solar winds and magnetic waves are not limited to outer space. Bursts of plasma emanating from the sun, for instance, can temporarily intensify electric ...

In theory, when the Earth rotates due to its own magnetic field, any electrically conductive material on its surface should feel the force that moves electrons, creating an electric current. However, ...

The Barrett Chute refurbishment is part of OPG’s w ider effort to upgrade its hydro fleet, which provides about 20% of ...

When set spinning, the setup mimics the roiling liquid iron in the Earth’s outer core, which forms electrical currents that generate the magnetic field in a process called a dynamo. His team ...
