Physicists have developed a minuscule instrument able to detect extremely faint magnetic fields. At the heart of the superconducting quantum interference device are two atomically thin layers of ...

Now more than ever, permanent magnets and electromagnets play a critical role in today’s advanced applications. From high-performance electric motors to magnetic nano-machines and high-reliability ...

Researchers show how magnetic flux sensors can be used to monitor the operation of proton exchange membrane fuel cells that run on hydrogen. By detecting changes in current, failure states due to ...

BERLIN—Measuring magnetic fields inside samples has only been possible indirectly up to now. Magnetic orientations can be scanned with light, X-rays, or electrons—but only on the surfaces of materials ...

A Superconducting Quantum Interference Device (SQUID) is an extremely sensitive magnetometer that measures very subtle magnetic fields. It exploits the quantum mechanical properties of ...

The last 50 years have seen the development of methods for the digital storage of information. The current method for the storage of digital information is predominantly through the use of magnetic ...

Sometimes you have to start out with big goals. Ninth-graders [Finja Schneider] and [Myrijam Stoetzer] are aiming to make a magnetic field scanner that would be helpful in finding large underground ...

Measuring magnetic fields inside samples has only been possible indirectly up to now. Magnetic orientations can be scanned with light, X-rays, or electrons - but only on the surfaces of materials.
