What is the Hall Effect? The Hall effect is a fundamental phenomenon in physics that occurs when an electric current flows through a conductor in the presence of a magnetic field perpendicular to the ...

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 ...
