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 ...

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 ...

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 ...

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 ...
