We’re used to Hall effect devices as proximity sensors in mechanical systems, used to provide detection of something that has a magnet attached to it. However it’s easy to forget that the ...

For years, Steven Murdoch, a security researcher at University College London, had taken care not to put tickets or cards with magnetic stripes ... by part of a circular magnet within the customer ...

With no magnets around, the kirigami disk was way more compliant than one without cuts. But when a magnetic field was applied, it became more than 1.8 times stiffer. Overall, the kirigami dome ...

Because Earth's magnetic field is slightly asymmetrical and more complex than that of a regular bar magnet, the magnetic south pole — the point in the Southern Hemisphere where the magnetic ...
