Quantum computation + quantum sensing = a new way to think about measurement on the tiniest scale, say researchers.

The reversal could actually have a beneficial effect on Earth. The sun is on the verge of a significant event: a magnetic field reversal. The sun undergoes such a reversal every 11 years ...

A magnetic field is the effect we can see from the movement of charges or the spin of electrons. The fields themselves can be static or changing. A field diagram can be used to show the interactions ...

At first glimpse, it may seem like infant stars and supermassive black holes have very little in common. Infant stars, or "protostars," haven't yet gathered enough mass to trigger the nuclear ...

To create 2D images, a mechanical gantry rotates the magnets and shift coils at 6 RPM, enabling imaging every 5 s. The MPI system also incorporates a water-cooled 26.3 kHz drive coil, which produces ...

Researchers at the University of Colorado Boulder (CU Boulder) have made a significant advance in magnetic field measurement. They have developed a new technique that uses atoms as highly precise ...

It was originally developed for CERN scientists. Rolex Magnetic fields are one of the most common factors negatively affecting the accuracy of a mechanical watch. Internal watch parts made of metal ...

Once the initial magnetic field is established ... Another challenge is vortex damping, a phenomenon where oscillating systems lose energy over time due to external forces. In maglev cars ...

Our physics expert picks his top-five equations, plus a scheme to supply US power needs with a bucket of baseballs. Thanks, ...

In mid-December of 2024, scientists officially updated the World Magnetic Model (WMM), which helps keep track of our planet’s magnetic north and its chaotic and relatively unpredictable movements.
