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 ...

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

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

A perfectly preserved ancient tree fossil offered scientists an unprecedented view into a moment 42,000 years ago when the Earth’s magnetic field went haywire. The compelling 2021 study tells the ...

An international team of scientists have modelled formation and evolution of strongest magnetic fields in the Universe.

An international team of scientists has modeled the formation and evolution of the strongest magnetic fields in the universe.

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 ...

Scientists say the discovery of this dynamo-like mechanism ... universe's most powerful magnetic fields, often hundreds of trillions of times more powerful than Earth's magnetosphere.

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 ...
