Hannes Alfvén (Nobel Prize winner)

Hannes Alfvén was a Swedish physicist who won the Nobel Prize for discovering how magnetic fields interact with conducting fluids like plasmas. He developed the concept of Alfvén waves—oscillations in plasma caused by magnetic forces—which are fundamental in understanding phenomena such as solar flares, solar winds, and the behavior of Earth's magnetosphere. His work helped explain how energy and particles move in space environments, impacting fields like astrophysics and space weather forecasting. Essentially, Alfvén revealed the magnetic dynamics shaping much of the universe's plasma behavior.
