The Earth’s magnetic field shows marked variations in the polar regions, which are more susceptible to auroral activity and geomagnetic storms. These factors may influence satellite and aircraft ...

The Earth’s magnetic field is currently weakening, and there’s been a lot of talk in recent years that a reversal might be imminent. Now a new study has looked at the history of these events ...

The generally weak emissions from the polar region have been much stronger, which makes it easier to obtain coronal magnetic field results in the polar regions. [Related: Rare quadruple solar ...

After sunspot cycle 23, the Sun went into a prolonged minimum characterized by a very weak polar magnetic field and an unusually large number of days without sunspots.

The Earth's changing, irregular magnetic field is causing headaches for polar navigation. Your friend's email. Your email. I would like to subscribe to Science X Newsletter. Learn more.

UC Davis researchers studying cores of sediment collected 40 years ago have found evidence for magnetic field vortices in the Earth's core beneath the South Pole. The results contrast with earlier ...

During a magnetic field reversal, "the sun's polar magnetic fields weaken, go to zero and then emerge again with the opposite polarity," explained solar physicist Phil Scherrer, also at Stanford ...
