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 ...

In 1845, Michael Faraday discovered what’s known today as the Faraday Effect—which describes how light and electromagnetism are related. A new study revealed that the magnetic component of light ...

Why there’s a need to assess current-flow distribution. How an arrangement was made for the measurement using a controlled magnetic field, laser-induced current flow, and a subtle physics-materials ...

The origins of magnetic steel can be traced back to the 18 th century when scientists began experimenting with iron alloys. In 1820, Hans Christian Oersted's accidental discovery of electromagnetism ...
