In physics, the classical "Hall effect," discovered in the late 19th century, describes how a transverse voltage is generated when an electric current is exposed to a perpendicular magnetic field.

Physicists have forced light to behave like electrons trapped in a magnetic field, producing a quantized sideways drift that had never been observed in photons before. The experiment, carried out on ...
