The device for determining the orientation of the magnetic field functions like a compass. If you hold it against a magnet (here, silver-grey), the blue-red pin rotates so that its red end points in the direction of the north pole. CREDIT Paul Scherrer Institute/Mahir Dzambegovic

Measuring strong magnetic fields using neutrons

In the future, it will be possible to measure the fields of magnets that are already installed in devices and thus are inaccessible by other probing techniques.

Astrophysical shock phenomena reproduced in the laboratory

The lab-scale experiment could help scientists understand interstellar and galactic-scale smashups.

Researchers Control Soft Robots Using Magnetic Fields

Conventional robotic grippers struggle to handle items that are delicate and of varying size, shape, and weight. So, scientists had built soft robotic grippers...
