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 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 ...

NASA scientists have discovered an electric field encompassing Earth’s atmosphere that is as “fundamental” as gravity — and could even give clues about possible life on other planets. A team of NASA ...

Researchers have demonstrated an innovative method to control magnetism in materials using an energy-efficient electric field. The discovery focuses on materials known as magnetoelectrics, which offer ...

An international team of scientists at NASA and other institutions say they’ve discovered a weak, planet-wide electric field wrapping the Earth that was first hypothesized by researchers decades ago.

A strange electric field around the Earth, long suspected to exist, has been detected for the very first time, and it is believed to cause a polar wind which launches particles into space at ...

Earth has a global magnetic field that’s flinging tiny bits of our atmosphere out into space. Researcher’s from NASA’s Goddard Space Flight Center recently launched a rocket high into the sky over the ...
