This persnickety number determines the strength of magnetic fields. It figures in everything from motors and generators to audio speakers. Oh, and without it we’d live in eternal darkness.

Beta Technologies' Alia electric aircraft finished a three-month experimental deployment with the U.S. Air Force that included a simulated casualty evacuation at Moody Air Force Base in Georgia. (Beta ...

NASA scientists have discovered a third global energy field around Earth. Known as the ambipolar electric field, this force drives charged particles into space above the poles. Two major global energy ...

Beta Technologies' Alia electric aircraft completed a three-month trial with the U.S. Department of Defense at Eglin Air Force Base, involving various missions and assessments by Air Force pilots. The ...

Water has always responded well to sunlight, evaporating faster under the sun than when heated by other energy sources. For ...

An electric charge (like a proton) creates an electric field in the region around it. This field points away from positive charges and decreases in strength as it gets farther away from the charge.

However, even high-quality 2D materials can have atomic defects, like missing sulfur or selenium atoms, which affect electrical behavior. The researchers corrected this with a chemical treatment using ...

Electric-field-assisted assembly enables scalable, lithography-free fabrication of logic circuits using 2D semiconductors. It ...

For more than a century, physics has been built on two great theories. Einstein's general relativity explains gravity as the ...

Glass embedded with electric-field-driven electrodes removes dust from its surface without water or scrubbing, offering a durable, passive cleaning solution for solar panels and other exposed optical ...
