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

Air Force researchers are working on an intriguing alternative based on maps of the Earth's magnetic field. The GPS systems the U.S. military relies on are vulnerable to jamming, spoofing and ...

The Earth's magnetic field surrounds our planet like an invisible force field—protecting life from harmful solar radiation by deflecting charged particles away. Far from being constant, this ...

This is called a magnetic dynamo, and is one of the most common ways of making strong magnetic fields throughout the cosmos. It's pretty cool that we have an example of it right underneath our feet.

Like the plot of a sci-fi B movie, something weird is happening deep underground where the constant spin of Earth's liquid metallic core generates an invisible magnetic force field that shields ...

Wire 2 is in the presence of this magnetic field, so it experiences a force that pulls it toward wire 1. The reverse is also true, which means that wire 1 is attracted to wire 2.

Constant magnetic force separation systems, such as Sepmag, produce a magnetic field pattern using a high magnetic force and gradient. This is done by employing arrays of permanent magnets, ...

Jupiter's magnetic field is profoundly different from that of all other known planets — it essentially has two magnetic south poles instead of just one, a new Nature study finds.
