This video presents the analytical solution for the electric field along the axis of a uniformly charged disk. Starting from Coulomb’s law, we derive the exact expression and discuss its physical ...

A breakthrough by researchers at The University of Manchester sheds light on one of nature's most elusive forces, with wide-reaching implications for medicine, energy, climate modeling and more. The ...

A dead satellite can become a high-speed hazard in an orbit that is already packed with working spacecraft. That risk is why ...

In this video, we walk through the full analytical derivation of the electric field produced by a uniformly charged ring. Using symmetry and Coulomb’s law, we derive the exact on-axis field expression ...

As the Parker Solar Probe ventures closer to the sun, we are learning new things about our home star. In a new study, physicists led by the University of Iowa report the first definitive measurements ...

This remarkable miniature rotorcraft is so lightweight and efficient that it can lift its own mass given nothing but sunlight. The entire thing weighs about as much as four paperclips, and it can fly ...

Princeton researchers have created a device that can herd groups of cells like sheep, precisely directing the cells’ movements by manipulating electric fields to mimic those found in the body during ...
