This still leaves that earlier puzzle, however: How did the early Earth produce its magnetic field? Today, that field is produced by the dynamo effect generated by electrical currents in the ...

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

Energy is needed to keep the dynamo running. This energy comes ... Without the effects caused by the spinning Earth, the magnetic fields generated within the liquid core would cancel one another ...

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 ...

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 By Walter M. Elsasser ...

A breakthrough simulation reveals how magnetars form and evolve, solving a key mystery about their magnetic origins.

Convection is "the engine that powers the dynamo that converts kinetic energy into magnetic energy and maintains Earth's global magnetic field," ScienceAlert explains. "That magnetic field is ...

An international research team, including the University of Geneva (UNIGE), has for the first time used numerical simulations ...
