When an electric current passes through a metal wire, a magnetic field forms around that wire (see diagram at right). Likewise, a wire passing through a magnetic field creates an electric current ...

A magnetic field is just an electric field seen from a different frame of reference. So, when an electron moves in the electric field of another electron, this special relativistic effect results ...

electric fields, temperature, and pressure at the nanoscale. This illustration represents the atomic structure of a diamond lattice. Included is a Nitrogen (N) Vacancy (V) center. (Image: Wikimedia ...

Dr. Barriga and colleagues found that cells of the neural crest are directed by internal electric fields during development, much like drivers follow the signals of a traffic warden. The group ...
