The Earth’s magnetic field, a silent guardian against harmful solar radiation, has been behaving strangely in recent years.

This persnickety number determines the strength of magnetic fields. It figures in everything from motors and generators to ...

All galaxies contain magnetic fields. The Milky Way’s field is most intense near its center, where its strength is about 1/20,000th the strength of Earth’s magnetic field.

Researchers recently discovered that the strength of the magnetic field required to elicit a particular quantum mechanical process corresponds to the temperature of the material. Based on this ...

New computer simulations suggest the first magnetic fields that emerged after the Big Bang were much weaker than expected — ...

A recent study published inScience Advances reveals that a temporary collapse of Earth’s magnetic field, known as the ...

The sun’s wispy upper atmosphere, called the corona, is an ever-changing jungle of sizzling plasma. But mapping the strength of the magnetic fields that largely control that behavior has proved ...

The researchers traced the subtle influence of "primordial magnetic fields" on the cosmic web, the vast, filamentary ...

New research suggests that the largest magnetic fields in the universe originated through some exotic mechanism that absolutely soaked the early cosmos.

Researchers recently discovered that the strength of the magnetic field required to elicit a particular quantum mechanical process, such as photoluminescence and the ability to control spin states ...
