Electric current is deflected by a magnetic field -- this leads to the so-called Hall effect. A surprising discovery has now been made: an exotic metal was examined and a giant Hall effect was found ...

The quantum Hall effect, a fundamental effect in quantum mechanics, not only generates an electric but also a magnetic current. It arises from the motion of electrons on an orbit around the nuclei of ...

Electric and magnetic fields are both components of an electromagnetic field. These two components occupy different planes relative to the cause of the electromagnetic field, for example a moving ...
