Earth’s magnetic north pole has been shifting gradually for centuries due to the movement of molten metals in the planet’s outer core. In the 1990s, magnetic north began to experience an ...
The planet's magnetic North Pole, where compasses point, has been unexpectedly moving toward Russia. While shifting is not a rare occurrence, the pole is moving both faster and differently than it ...
Geographic north, which is a straight line between wherever you are on the planet and the (geographic) North Pole, doesn’t actually point at the north magnetic pole at all. It’s a bit ...
The Earth's magnetic North Pole is moving east, which is interesting but not unusual. What's unusual is how fast it is moving. At 55 kilometres a year, the pole is racing east at a pace faster ...
Now, new research suggests that a magnetic pole flip roughly 42,000 years ago brought with it some dramatic changes, and may have changed the course of human history. Disaster movies have shown us ...
paleomagnetic records show that the intensity drops by up to 90 percent in the process of pole-switching. We should all feel grateful that we live in a time of magnetic stability, because the field ...
But it’s more important than you might think. The Earth acts like a giant bar magnet, with a magnetic north and south pole. Confusingly, these are not in the same place as the geographic north ...
If you bring a north pole and a south pole together, they will attract. Earth's core contains liquid iron which moves around. Iron is magnetic so the liquid iron causes Earth to have a magnetic field.
Scientists have known about these dramatic magnetic pole events for a long time but it’s never been clearly understood what kind of impact they have on life or the environment. That is until a ...
Some animals that migrate across the globe — such as birds, salmon, and lobsters — are known to navigate using the magnetic field lines that stretch from Earth’s north to south pole.
