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 ...

FROM a knowledge of the mass of the Earth and its moment of inertia and from an analysis of seismic data, Bullen 1 has reconstructed a pressure-density curve for the Earth's interior. The outer ...

The Earth's magnetic field quietly supports life on the planet and now, for the first time, its invisible powers have been used to create new nanoparticles and materials. Scientists at Flinders ...

The team found that the North Pole wandered over Europe when the magnetic field's poles started to flip positions, a natural process that has happened around 180 times over Earth's geological history.

The strength of Earth’s magnetic field dropped to just 10% of its current level, while the magnetic poles wandered far from their usual locations. For about 300 years, the magnetic fi ...

This can interact with another magnetic field, causing a force that pushes the wire at right angles. This is called the motor effect. Figure caption, There is a force at right angles to the ...

The earth’s solid iron core is hot enough to demagnetize iron and its alloys. So how does it generate the geomagnetic field? John Campbell, Hood River, Oregon Its core doesn’t. The geomagnetic ...
