The Earth's magnetic field is generated by the complex interplay of convective flows in its liquid outer core, a process commonly referred to as the geodynamo. The dynamics of this magnetic field ...

Earth’s trusty magnetic field has been keeping the planet safe for at least 3.7 billion years. There’s a chance it might have formed even earlier than this, but the evidence is shaky and less ...

Essentially, a big boost of energy was needed to drive the geodynamo and stop the magnetic field from collapsing—and the solidification of Earth's core would have done just that.

Earth’s magnetic field has correlated with fluctuations in atmospheric oxygen, according to a newly released study.

According to National Geographic, for a planet to generate its own magnetic field by the geodynamo process, ... Learn more about Earth's magnetic field with this short video from Arbor Scientific.

Life as we know it could not exist without Earth's magnetic field and its ability to deflect dangerous ionizing particles. It is continuously generated by the motion of liquid iron in Earth's ...

Earth's magnetic field is fading. Today it is about 10 percent weaker than it was when German mathematician Carl Friedrich Gauss started keeping tabs on it in 1845, scientists say.

earth's magnetic field 4 billion years ago Previous research by Tarduno found that Earth's magnetic field is at least 4.2 billion years old and has existed for nearly as long as the planet.

Earth's magnetic field is powered by what scientists call the "geodynamo." That's the movement of the iron-rich outer core, which turns the planet into a giant, if somewhat messy, magnet.

The magnetic field is generated by swirling liquid metal in Earth's outer core, and this "geodynamo" requires ... Listen to the Andromeda galaxy's stars played as musical notes in eerie NASA video.

Most scientists believe our planet's magnetic field is sustained by what's known as the geodynamo. The term describes the theoretical phenomenon believed to generate and maintain Earth's magnetic ...
