It’s thus worth putting in the effort to make a better antenna, and if you’re not fortunate enough to have a lot of space, your best choice may be a magnetic loop. [Robert Hart] takes us ...
This self-sustaining loop is known as the geomagnetic dynamo ... which keeps the liquid metal moving through the magnetic field. The so-called Coriolis force also plays a role in sustaining ...
NASA has been monitoring a strange anomaly in Earth's magnetic field: a giant region of lower magnetic intensity in the skies ...
NASA scientists are concerned about a strange anomaly in Earth's magnetic field, which can make life at the International ...
This discovery offers a new explanation for the asymmetric hysteresis loop in Co 3 Sn 2 S 2, different from the usual EB effect. "By adjusting the maximum external magnetic field, we can control ...
They have shown the generation and application of magnetic field steps, in which a magnetic field is turned on in a matter of picoseconds. The work has been published in Nature Photonics.
Engineers at the University of Leeds have developed a tiny magnetic robot that could revolutionize early cancer detection.
There are two main types of SQUIDs: DC SQUIDs and RF SQUIDs. DC SQUID: A DC SQUID consists of two Josephson junctions connected in parallel in a superconducting loop. When an external magnetic field ...
