Quantum computers get a lot of attention, even though they are not ready for prime time, but quantum sensors are already doing useful work. These sensors measure fields, forces and motion so small ...

Muons might not behave as expected. But scientists can’t agree on what to expect. By taking stock of how the subatomic particles wobble in a magnetic field, physicists have pinned down a property of ...

Researchers in Japan have developed a highly-sensitive magnetic Barkhausen noise (MBN) measurement system to understand the energy loss mechanisms in soft magnetic materials, which can be easily ...

Using the superior sensitivity of ESA’s X-ray observatory, XMM-Newton, a team of European astronomers has made the first direct measurement of a neutron star’s magnetic field. The results provide deep ...
