Physicists in the US have developed a tiny portable device that is sensitive enough to detect the magnetic fields from electrical signals in the brain. Consisting of a cell filled with a vapour of ...

Variable reluctance (VR) sensors transform mechanical motion into electrical signals by exploiting changes in magnetic flux. As a ferromagnetic target moves past the sensor’s pole piece, the ...

NASA’s Parker Solar Probe is forcing scientists to rethink how the Sun’s magnetic machinery actually works. A series of ...

A Czech and Spanish-led research team has demonstrated the ability to distinguish subtle differences between magnetic ground states using a new form of scanning probe microscopy. Subscribe to our ...

A new 3D imaging technique using neutrons has been invented by physicists in Germany. The technique, which can visualize magnetic fields inside bulk objects, is an improvement on existing magnetic ...

A Southwest Research Institute-led study found that protons and heavy ions react differently to solar magnetic reconnection ...

In a recent study published in the journal Science Robotics, a team of researchers created a magnetic microrobot probe that can quantify the stiffness and traction force of tumor cell colonies and ...
