Learn how forces deep underground generate a protective bubble between us and space.

New research indicates that matter ejected during the supernova death of a star can fall back to neutrons stars, giving rise ...

Scientists have uncovered the long-sought mechanism behind low-field magnetars, showing that supernova fallback material ...

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 ...

Supernova debris speeds up neutron stars, strengthening magnetic fields. This explains why low-intensity magnetars still ...

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 ...

Earth's magnetic field is generated by mixing of the molten iron in the fluid outer core, driven by changes in density as as the inner core slowly solidifies, which creates a dynamo effect.

Noveon Magnetics Inc landed a deal to deliver 1,000 tons of magnets to Nidec Motor Corp. over five years. No terms were ...

This week, see what makes loggerhead sea turtles “dance,” track a cosmic “ghost particle,” uncover an ancient basilica, and more.

The mechanisms that sustain the Earth's magnetic dynamo, which has been active for over 3.4 billion years, have also been a subject of investigation. Various theories have been proposed ...

Earth's magnetic field occasionally bursts into song — but these compositions are written with electromagnetic radiation, not ...

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 ...
