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

Why is the earth a magnet? 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 Skip to main content ...

In the Earth (see image below right), the liquid metal ... This self-sustaining loop is known as the geomagnetic dynamo. Energy is needed to keep the dynamo running. This energy comes from the ...

Magnetars are a class of neutron stars with the strongest magnetic fields in the Universe. These incredibly dense objects are central in the landscape of extreme phenomena such as hypernovae, fast ...

The Tayler-Spruit dynamo mechanism is thought to convert the angular momentum of infalling plasma to magnetic fields within the neutron star. This is similar to how mechanical dynamos on Earth ...
