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 ...

NASA scientists are concerned about a strange anomaly in Earth's magnetic field, which can make life at the International Space Station difficult. The vast and evolving phenomenon is called the South ...

NASA has been monitoring a strange anomaly in Earth's magnetic field: a giant region of lower magnetic intensity in the skies above the planet, stretching out between South America and southwest ...

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 ...

This discovery offers a new explanation for the asymmetric hysteresis loop in Co 3 Sn 2 S 2, different from the usual EB ...

Get Instant Summarized Text (Gist) Micrometer-sized, flower-shaped structures made of a nickel-iron alloy can locally enhance magnetic fields by concentrating field lines at their center. The ...

The South Atlantic Anomaly (SAA) affects spacecraft that pass through the weak magnetic field area as they loop around Earth. The reduced magnetic field could result in disruption of technological ...

No matter how its done, with whatever level of fakery, magnetic levitation just ... with some control electronics to adjust the field strength and close the loop. But, there may be another way ...

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 ...

During a brief but dramatic chapter in Earth's history about 41,000 years ago, the planet’s magnetic field nearly collapsed. What followed was a cascade of environmental and biological changes ...
