Alfvén waves (AWs) are classified as low-frequency transverse electromagnetic waves that propagate along the lines of the magnetic field (MF). These waves can be generated in electrically conducting fluids, such as plasma.
Alfvén waves are a type of plasma wave that occur in magnetized plasmas, where ions oscillate due to the tension in magnetic field lines. They play a crucial role in various astrophysical phenomena, including energy transport in the solar atmosphere and particle acceleration.
