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 ...

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 ...

For the first time, scientists have measured a long-sought global electric field in the Earth’s atmosphere. This field, called the ambipolar electric field, was predicted to exist decades ago but ...

For as long as people have watched storms roll across the sky, lightning has inspired awe and fear. You can see the flash and ...

In 1832, Charles Darwin witnessed hundreds of ballooning spiders landing on the HMS Beagle while some 60 miles offshore. Ballooning is a phenomenon that’s been known since at least the days of ...

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 ...
