Earth’s inner core is changing shape, scientists have found.

The findings shed light on a deeply mysterious part of Earth that is key to life on our planet.

When an electric current passes through a metal ... the Earth's surface. These spiraling eddies allow separate magnetic fields to align (more or less) and combine forces. Without the effects ...

Earth’s magnetic field, generated by movements within its molten iron core, serves as a protective shield against solar winds ...

As this material is often conductive, it will likely affect the Earth’s magnetic field, as argued by [Sierra ... and ionosphere in particular with metal aerosols at levels never seen before ...

Earth's magnetic field occasionally bursts into song — but these compositions are written with electromagnetic radiation, not sound waves. When converted to audio signals, though, these strange ...

Earth's magnetic field is generated by mixing of the molten iron in the fluid outer core, driven by changes in density as as the inner core slowly solidifies, which creates a dynamo effect.

NASA has been tracking an evolving "dent" in Earth's magnetic field which ... to be what is disturbing the field's generation, resulting in the weakening effect. Stephen Hawking predicted exact ...

The reversal could actually have a beneficial effect on Earth. The sun is on the verge of a significant event: a magnetic field reversal. The sun undergoes such a reversal every 11 years ...

If the Earth's field is disrupted, it may cause problems in technology and navigation, as well as expose the planet to unwanted radiation. Magnetic poles move because the "liquid metal in the ...
