As sunspots emerge on the sun's surface close to its equator, their orientations will match the old magnetic field, while sunspots forming closer to the poles will have a magnetic field matching the ...

Your navigation system just got a critical update, one that happens periodically because Earth’s magnetic north pole keeps moving. Here’s what to know.

The sun is on the verge of a significant event: a magnetic field reversal. What causes this switch in polarity, and is it dangerous for anything on Earth? Let's take a deep dive into the ...

Iron is magnetic so the liquid iron causes Earth to have a magnetic field. The needle of a compass is a small magnet that can turn. It turns around until its own magnetic field lines up with the ...

Some of the most sensitive methods of measuring magnetic fields use interactions of resonant light with atomic vapour. Recent developments in this vibrant field have led to improvements in ...

The sun's magnetic field last flipped toward the end of 2013. What causes this switch in polarity, and is it dangerous for anything on Earth? Let's take a deep dive into the phenomenon of the sun ...
