This video presents the analytical solution for the electric field along the axis of a uniformly charged disk. Starting from Coulomb’s law, we derive the exact expression and discuss its physical ...

A dead satellite can become a high-speed hazard in an orbit that is already packed with working spacecraft. That risk is why ...

In this video, we derive the electric field between two charged plates using fundamental principles of electrostatics. Step-by-step reasoning, clear equations, and physical intuition are used to show ...

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 ...

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.

This remarkable miniature rotorcraft is so lightweight and efficient that it can lift its own mass given nothing but sunlight. The entire thing weighs about as much as four paperclips, and it can fly ...

Invisibly to us, insects and other tiny creatures use static electricity to travel, avoid predators, collect pollen and more. New experiments explore how evolution may have influenced this phenomenon.
