But the field is not as reliable as we first thought. There is strong evidence in the geological record to suggest that many times throughout the Earth’s history the north and south magnetic poles ...

The Earth's magnetic field is generated within the liquid core of our planet, by the slow churning of molten iron. Like the atmosphere and oceans, the way in which it moves is governed by the laws ...

Earth's magnetic field originates in the outer core and extends out into the magnetosphere — a region of space that helps protect Earth from space weather.

Further, physicists like Cohen say that the Earth’s magnetic field isn’t going to flip overnight. This is something that reverses on a time scale between 100,000 and 1,000,000 years.

Sunspots are the most striking phenomenon of the solar magnetic field. After the invention of the telescope early in the 17th ...

150,000-year history of Earth's magnetic field reveals clues about the climate when early humans were spreading out ... she has freelanced for New Scientist and the American Institute of Physics.

Like most planets in our solar system, the Earth has its own magnetic field. Thanks to its largely molten iron core, our planet is, in fact, a bit like a bar magnet.

During a brief but dramatic chapter in Earth's history about 41,000 years ago, the planet’s magnetic field nearly collapsed. What followed was a cascade of environmental and biological changes ...

Most magnetic fields on Earth, even artificial ones, are not particularly strong. The magnetic resonance imaging (MRI) used in hospitals typically produces fields of around 1 tesla, or 10,000 gauss.

Physicists in France have linked subtle variations in the length of day with conditions in the Earth’s core – where the Earth’s magnetic field originates. The finding could improve our poor ...
