Although the Earth’s magnetic field is reliable enough for navigation and is also essential for blocking harmful solar emissions and for improving radio communications, it’s not a uniform strength ...

A solar tsunami observed by NASA’s Solar Dynamics Observatory (SDO) and the Japanese Hinode spacecraft has been used to provide the first accurate estimates of the Sun’s magnetic field. Solar tsunamis ...

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 ...

A team of physicists and engineers at the University of Colorado Boulder has discovered a new way to measure the orientation ...

High school students in Portugal programmed a small, inexpensive Raspberry Pi computer to measure Earth's magnetic field from the International Space Station. When you purchase through links on our ...

Studies of a solar flare revealed something unexpected about the sun: its magnetic field is even stronger than scientists predicted. Measuring that magnetic field within loops of material bursting out ...

Physicists have developed a minuscule instrument able to detect extremely faint magnetic fields. At the heart of the superconducting quantum interference device are two atomically thin layers of ...

When you get an MRI scan, the machine exploits a phenomenon called nuclear magnetic resonance (NMR). Certain kinds of atomic ...

Two German physicists have reimagined how to create powerful and uniform magnetic fields using compact permanent magnets. By overcoming the limitations of the well-known Halbach array, which works ...
