In this video, we use Gauss’s law to find the electric field of a uniformly charged sphere. We derive the field both inside and outside the sphere, explain the symmetry behind the Gaussian surface ...

In this video, we derive the electric field of a long uniformly charged rod using Gauss’s law. We choose an appropriate Gaussian surface, apply symmetry arguments, and walk through the math ...

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 ...

High-speed imaging of charged droplet dynamics reveals a critical transition in the role of non-uniform AC electric fields on ...

NASA scientists have discovered a planet-wide electric field surrounding Earth, confirming a 60-year-old hypothesis. Studying the field could yield some vital information about how our planet's ...

In the home, the lab and the factory, electric fields control technologies such as Kindle displays, medical diagnostic tests and devices that purify cancer drugs. In an electric field, anything with ...
