Antennas come in many shapes and sizes, with a variety of characteristics making them more or less suitable for various applications. The average hacker with only a middling exposure to RF may be ...

The average Hackaday reader likely knows, at least in the academic sense, what a magnetic field looks like. But as the gelatinous orbs in our skull can perceive only a tiny fraction of the EM spectrum ...

Simulations and satellite data reveal that Earth's magnetic field is more complex than scientists had thought. Scientists ...

Applying a magnetic field to PdCo2, a non-magnetic metal, made it conduct 70% more electricity, even though basic physics principles would have predicted the opposite. Insights from pure mathematics ...

Inductive sensors achieve fast response times. Changes in position or speed cause immediate alterations in the induced eddy currents, which directly affect the inductance of the sensor coil. This ...

Throughout any given year, the National Academies convene hundreds of conferences, workshops, symposia, forums, roundtables, and other gatherings that attract the finest minds in academia and the ...

Honey bees appear to sense magnetic fields using a magnetic structure in their abdomens, according to a team of physicists and biologists in Canada. The researchers came to this conclusion by carrying ...
