The moody sound bite comes from the magnetic field generated by Earth’s core and its interaction with a solar storm.Earth’s magnetic field is essential to life on the planet, but it isn’t ...

The Earth’s magnetic field is considered vital for life, ... which posits that in a rotating core flows occur perpendicular ...

A magnetic field created by the outer core generates the spin and the mantle’s gravitational effects balance it out. Understanding how the inner core rotates could shed light on how all of the ...

Deep within the Earth, at pressures nearing 350 gigapascals and temperatures exceeding 6000 Kelvin, iron flows in the ...

During this transition, heat is released, generating the Earth’s magnetic field. This, plus the gravity exhibited by the mantle, causes the inner core to spin.

Earth’s magnetic field, ... Afterward, the inner core’s spin decelerated until its rotation appeared to have stopped at some point between 2009 and 2011.

In the mid-1990s scientists found evidence that Earth’s inner core, a superheated ball of iron slightly smaller than the moon, was spinning at its own pace, just a bit faster than the rest of ...

Earth’s magnetic field yanks at this solid ball of hot metal, making it spin. At the same time, the gravity and flow of the fluid outer core and mantle drag at the core.

The Earth's magnetic field is essential to life as we know it. But it’s something we can never see – or hear, until now. In a recent study released on Oct. 10 by the European Space Agency ...

When set spinning, the setup mimics the roiling liquid iron in the Earth’s outer core, which forms electrical currents that generate the magnetic field in a process called a dynamo.

Geophysics models explain that, since the movement of a liquid metal induces electrical currents, and currents induce a magnetic field, convection and rotation produce our planet’s magnetic fields.

The Earth’s magnetic field is considered vital for life, ... which posits that in a rotating core flows occur perpendicular to the axis of rotation, making a series of concentric cylinders.
