During solar minimum, the sun's magnetic field is close to a dipole, with one north pole and one south pole, similar to Earth's magnetic field. But as we shift toward solar maximum, "the sun's ...

The magnetic north pole, where compass needles point, is about 1,200 miles south and is where geomagnetic field lines are vertical. Earth’s magnetic north is not static. Like an anchorless buoy ...

Thus, if we can date the rocks, we can tell north from south in that era. Reversals don’t happen instantly, but over a period of thousands of years as the magnetic field gradually weakens. Though its ...

If the Earth's field is disrupted ... are monitoring is the potential for a full magnetic reversal, during which the North and South Poles would flip entirely. While this has occurred many ...

The magnetic field is shown by lines with arrows that point from north to south. You can tell how old some coins are by testing them with a magnet. 5p and 10p coins made before January 2012 are ...

It took 250 years for the Laschamps reversal to take place and it stayed in the unusual orientation for about 440 years. At most, Earth's magnetic field may have remained at 25 percent of its current ...

Some animals that migrate across the globe – such as birds, salmon, lobsters and sea turtles – are known to navigate using the magnetic field lines that stretch from Earth's north to south pole.
