The Earth’s magnetic field, a silent guardian against harmful solar radiation, has been behaving strangely in recent years. This has sparked many questions and concerns about the implications of such ...

New computer simulations suggest the first magnetic fields that emerged after the Big Bang were much weaker than expected — containing the equivalent magnetic energy of a human brain.

This persnickety number determines the strength of magnetic fields. It figures in everything from motors and generators to audio speakers. Oh, and without it we’d live in eternal darkness.

Long before galaxies sparkled in the sky or stars took shape, invisible forces stirred in the early Universe. One of those ...

Since the Big Bang, magnetic forces have existed as a natural force with the movement of charged particles. For a long time, scientists believed that these primordial magnetic fields (also known as ...

The polarization pattern around M87* — the first black hole to be directly imaged by the Event Horizon Telescope — has ...

A high-resolution image of the magnetic field in the El Gordo cluster, including the Chandra X-ray image (blue part of the image), the NASA JWST infrared image (background galaxies of the image), and ...

As a result of the tetrahedral symmetry of the lattice, a diamond crystal typically contains NV centers in four orientations.
