The idea of electric field was introduced by Michael Faraday. The electrical field force acts between two charges, in the same way that the gravitational field force acts between two masses. The ...

An electric charge (like a proton) creates an electric field in the region around it. This field points away from positive charges and decreases in strength as it gets farther away from the charge.

A nematode (C. elegans) jumps onto a bumblebee along an electrical field to hitch a ride. Credit: Chiba et al., 2023 Japanese scientists working with nematodes (C. elegans) noticed one day that ...

Erasable electric fields written by laser light onto crystal surfaces can trap, align, and release living cells without ...

In Python Physics #27, we break down the concept of electric potential using point charges and Python simulations. Learn how to calculate and visualize the potential created by single and multiple ...

In Python Physics #22, we bring electric fields of a point charge to life with interactive Python simulations. Learn how to visualize field lines, understand the direction and magnitude of the ...

Electromagnetic fields as they would be generated by positive and negative electric charges, both at rest and in motion (top), as well as those that would theoretically be created by magnetic ...
