Interesting formations: an example of droplet shapes that are produced when an electric field is applied to an oil mixture. (Courtesy: Aalto University) When a simple system of two liquids is driven ...

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 ...

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 ...

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 ...

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 ...

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 ...

Physicists have described in fuller detail the sun's electric field. The researchers measured the flow of electrons streaming from the sun as the Parker Solar Probe spacecraft made its closest ...

Stephen has degrees in science (Physics major) and arts (English Literature and the History and Philosophy of Science), as well as a Graduate Diploma in Science Communication. Stephen has degrees in ...

For about 20 years, Caltech Professor of Applied Physics Paul Bellan and his group have been creating magnetically accelerated jets of plasma, an electrically conducting gas composed of ions and ...
