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 ...

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 ...

In this interview, Dr Ventsislav Valev talks to AZoNano about his research on "hotspots" in electrical fields on nanostructured surfaces, which have applications in catalysis, sensors and analytical ...

Controlling magnetic properties by an electric field would enable new data storage technologies operating at low electrical power 1,2. Successful strategies have made use of voltage‐controlled ...
