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 coil of wire, or solenoid, consists of a wire coiled up into a spiral shape. When an electric current flows, the shape of the magnetic field is very similar to the field of a bar magnet.

Indeed there is, in addition to the obvious ways to manipulate the spin using magnetic fields, an indirect effect on the electron spin from externally applied electric fields, due to the so-called ...

Accompanying those electrical signals are tiny magnetic fields that have only recently been tapped for information into how the human body works. “Our natural magnetic fields offer a different ...

Electric currents generate magnetic fields, and current-carrying wires interact magnetically. Upon exploring how changing magnetic fields induce electric fields, one must question whether changing ...
