The Keeble Observatory at Randolph-Macon College holds weekly public viewing during spring semester. Check their website ( or ...

In the Earth (see image below right), the liquid metal that makes up the outer core passes through a magnetic field, which causes an electric current to flow within the liquid metal. The electric ...

Earth's main magnetic field is generated in the planet's outer core, a layer of molten iron 2,2001,800-3,100 miles (2,890-5,000 kilometers) below the planet's surface. The electrically conductive ...

Surprising differences in the two so-called Large Low-Velocity Provinces may risk instability in Earth's protective magnetic field.

Here, the convective movement of electrically charged, molten iron in the outer core produces electrical currents, generating the magnetic field. Understanding this geodynamo mechanism requires ...

Its solidification causes convection in the outer core. Convection is "the engine ... magnetic energy and maintains Earth's global magnetic field," ScienceAlert explains. "That magnetic field ...

The outer core is liquid iron and nickel and generates the Earth's magnetic field. And the inner core is made of solid iron and nickel. The surface of the earth is constantly changing. It's the ...

If the Earth's field is disrupted ... as well as expose the planet to unwanted radiation. Magnetic poles move because the "liquid metal in the outer core is sloshing around instead of holding ...

The answer depends on where you are in the cosmos and what other magnetic fields are at play. On Earth, a compass needle aligns with our planet’s geomagnetic field, which is generated by the movement ...

A weak magnetic field likely attracted matter inward, contributing to the formation of the outer planetary bodies, from ...
