Their simulated scenario is as follows. The Earth’s magnetic field is generated deep in its interior by the molten core spinning around. This is the geodynamo. The Moon, too, might have had a ...

Today the magnetic field is more or less aligned with Earth’s rotational axis (each pole lies about 11 degrees off from the geographic poles). But it isn’t fixed in place — the complex motions of the ...

It is generated by the geodynamo effect. "We know that the Earth's core is primarily composed of iron," explains Attila Cangi, Head of the Machine Learning for Materials Design department at CASUS.

For example, around 3.9 billion years ago, Mars' geodynamo mysteriously slowed down, dramatically weakening its magnetic field, which eventually resulted in the loss of its atmosphere.

Mars' global magnetic field may have hung around for 200 million years longer than scientists had thought, possibly giving life a longer window to take hold on the Red Planet.

The outer core and the geodynamo Earth’s outer core has a radius of around 3,480km, which makes it slightly bigger than the planet Mars.

A peculiar property of the Earth’s magnetic field could help us to work out how our planet was created 4.5 billion years ago, according to a new scientific assessment.

The core results also indicated that Mars’ core would have cooled quicker than Earth’s, potentially creating the geodynamo that sustained a Martian magnetic field for a time.

Earth’s supply of radioactive elements provides more than enough internal heating to generate a persistent geodynamo, according to Francis Nimmo, professor of Earth and planetary sciences at UC Santa ...

The Earth's geodynamo is something that scientists around the world are curious about because it contributes to the planet's habitability.

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.
