In plasma physics, an Alfvén wave, named after Hannes Alfvén, is a type of plasma wave in which ions oscillate in response to a restoring force provided by an effective tension on the magnetic field lines. Discovered theoretically by Alfvén in 1942—work that contributed to his 1970 Nobel Prize in Physics—these waves play a fundamental role in numerous astrophysical and laboratory plasma phenomena.
