Invisibility has quietly shifted from fantasy to engineering problem, and the most convincing proof is not a shimmering cape but a magnetic cloaking device that makes fields themselves vanish from ...

University of Leicester engineers have unveiled a concept for a device designed to magnetically "cloak" sensitive components, making them invisible to detection. A magnetic cloak is a device that ...

Magnetic fields are all around us. We can’t really feel or see them ourselves, per se, but we can map them with the right hardware, like this device built by [edosari50]. The build uses an ESP32 ...

3D and cross-sectional views of an optimized Superconducting (SC)- Soft-Ferromagnetic bilayer (SFM) cloak. At the left no SFM is used showing the diamagnetic response of the SC. At the right the ...

Materials with magnetic nanostructures have a wide range of potential applications. One area is so-called spintronics, with ...

An imperfect diamond is perfect for sensing Earth’s magnetic field from space. A quantum device used a diamond’s defects to map Earth’s magnetic field from the International Space Station. Just 10 ...

Magnetic storage devices, like a computer's hard disk drive, utilize magnets to represent binary data. However, as these ...
