Near-field electromagnetic measurement techniques probe the region immediately around radiating structures, where reactive and radiative field components coexist. By scanning a dedicated probe across ...

Electric field measurement in power systems underpins critical activities from asset monitoring to safety assurance. Techniques span optical, inductive and microfabricated approaches, each offering ...

Neutron stars have the strongest magnetic fields in the universe, and the only way to measure their surface magnetic field directly is to observe the cyclotron absorption lines in their X-ray energy ...

Insight-HXMT’s discovery of the fundamental electron cyclotron absorption line near 146 keV for the first Galactic ultraluminous X-ray pulsar Swift J 0243.6+6124. Neutron stars have the strongest ...

A research team has, for the first time, realized the quantum amplification of an extremely weak magnetic field by using dark spin, with the magnetic field magnification exceeding a factor of 5,000 ...

Add Yahoo as a preferred source to see more of our stories on Google. Researchers at the University of Colorado Boulder (CU Boulder) have made a significant advance in magnetic field measurement. They ...

When Scotty is beaming up, he’s working in the very far field. Distinguishing between near field and far field conditions is especially important in EMC testing. Published antenna factors and related ...

In-plane magnetic fields are responsible for inducing anomalous Hall effect in EuCd₂Sb₂ films, report researchers from the Institute of Science Tokyo. By studying how these fields change electronic ...

Imagine a satellite, floating in space. How would you measure its voltage? Yes, it probably has a non-zero voltage, a consequence of geospatial electric fields and ion and electron currents. The ...

It is not known when humans first noticed the attraction or repulsion between pieces of magnetic material. The first important device depending on these forces was the magnetic compass, which is ...
