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 ...

In the Earth (see image below right), the liquid metal that makes up the outer core passes through a magnetic field, which causes an electric current to flow within the liquid metal. The electric ...

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.

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 ...

Could the expected solar flares bring a greater chance of seeing the northern lights? Sophia Herod takes a look.

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 ...

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 ...

then in a more recent twist rapidly slowed — though scientists can’t explain the underlying cause behind the magnetic field’s unusual behavior. Global positioning systems, including those ...
