Understand the change in electric potential for a constant electric field and a point charge. This video explains the core concepts, key equations, and how electric potential varies with position in a ...

During the 1960s, spacecraft traveling above Earth's poles discovered a stream of particles flowing out of the Earth's poles, and theorized that there must be an unknown field driving these particles ...

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 ...

NASA scientists have discovered a third global energy field around Earth. Known as the ambipolar electric field, this force drives charged particles into space above the poles. Two major global energy ...

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 ...

Researchers at Paul Scherrer Institute PSI have demonstrated an innovative method to control magnetism in materials using an energy-efficient electric field. The discovery focuses on materials known ...

While it may be an unfamiliar sensation to humans, electroreception is relatively commonplace in the animal kingdom. Sharks, bees and even the platypus all share this ability to detect electric fields ...

Detailed measurements collected in metropolitan Tel Aviv, Israel, have revealed how the ebb and flow of traffic throughout the week affects the electric field generated by Earth's atmosphere. Led by ...
