New research conducted by an international team of physicists has found that high-energy gamma rays might offer the key to unlocking the mysteries of the sun's magnetic fields. The study, led by the ...

Abstract: The topology of magnetic field due to a filamentary current carrying conductor is not very difficult to follow and rich literature gives a number of clues to estimate the field at desired ...

The U.S. Department of Defense (DoD) is aware of the need for reliable navigation and the susceptibility of the Global Positioning System (GPS) to ineffectiveness due to jamming. As a result, the ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

ANN ARBOR, Mich. — Earth’s Northern Lights typically dance near the poles, but 41,000 years ago, they lit up skies over North Africa and Australia. New research reveals how dramatically Earth’s ...

Flower-shaped magnetic metamaterials are being used to boost the power of magnetic sensors and imaging tools by focusing magnetic fields with pinpoint precision. Credit: SciTechDaily.com Tiny magnetic ...

Researchers show that Cartan's First Structure Equation links crystal defects to the same mathematical rules governing electric currents and magnetic fields. (Nanowerk News) A fundamental goal of ...

Battling a head cold, Merritt cradled a stuffed animal through the performance (a white cat you can spot sitting on the Desk in a lot of Tiny Desk sets). "I don't actually know whose cat this is," he ...

During Thursday's "severe" geomagnetic storm that sparked the northern lights across most of the U.S., electrical currents surged through rocks under the ground around the country. A map from the ...
