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.
