Oscillations of the magnetic field around one of these substances are known as Alfvén waves.
Oscillations of the magnetic field around one of these substances are known as Alfvén waves. An important parameter governing these is the length over which charge separation occurs, known as the Debye (DEB-yuh) length. First observed by William Crookes, common examples of this substance include auroras, (*) lightning, and fire, and it is thought to make up 99% of the universe. Name this material phase, a collection of free ions often called "the fourth state of matter."
