Alfven Wave

Alfvén waves are a type of magnetic wave that travel through plasma, which is a hot, ionized state of matter like the Sun or space. They occur when magnetic field lines within the plasma oscillate, causing the particles to move along the magnetic lines in a wave-like pattern. These waves carry energy and momentum, influencing space weather and helping transfer energy from the Sun's surface to its outer atmosphere. Think of them as magnetic "strings" that ripple and shake, transmitting energy across vast distances in space plasmas.
