has demonstrated how Earth's magnetic field may be influencing internal flow, using what they describe as a Little Earth Experiment. In their study published in the journal Physical Review Letters ...

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 ...

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

Christopher Chyba held a hollow, dark cylinder made of manganese, zinc, and iron in his Princeton lab, looking skeptically at ...

New research led by a York University professor sheds light on the earliest days of Earth's formation and potentially calls ...

Back in 1832, the celebrated British physicist, Michael Faraday, carried out a set of experiments designed to answer a tantalizing question: could electricity be generated by Earth's rotation through ...

Most of the time, the Earth and Sun’s magnetic fields are misaligned, leaving our planet’s field less open to the ...

Scientists have some possible explanations, including "changes in the flow of molten ... understanding of Earth's geodynamo, which is the engine behind the magnetic field that shields us from ...

The best places to see the auroras, especially on Tuesday night, will be across central regions of the country — Labrador, ...

The best answer at present is that the slow flow of matter in its fluid core generates electric currents, which in turn set up a magnetic field By Walter M. Elsasser Join Our Community of Science ...

The Analyzer for Cusp Electrons (ACE) is designed to measure electron activity in the region of the northern magnetospheric ...

The stronger the magnetic field, the farther apart the line ... Earth's auroral electrojets—intense electric currents that flow high above Earth's polar regions when auroras glow in the sky.
