A hands-on physics lab exploring how to plot electric fields and electric potential. Visualize how charges influence space ...

Fleeting electron-hole pairs are giving scientists a new window into optimizing light-emitting devices (LEDs). Using quantum ...

In this video, we compute and visualize the electric field from two charges using Python, showing how to calculate field vectors and plot the results clearly. Perfect for learning electrostatics, ...

We all use antennas for radios, cell phones, and WiFi. Understanding how they work, though, can take a lifetime of study. If you are rusty on the basic physics of why an antenna radiates, have a look ...

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 ...

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 ...

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 ...

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 ...

Researchers directly observed electron-hole pairs in light-emitting electrochemical cells, finding that ion-driven electric field changes affect recombination and that stable, lower-voltage fields ...
