Plasma Physics presents an authoritative and wide-ranging pedagogic study of the 'fourth' state of matter. The constituents of the plasma state are influenced by electric and magnetic fields, and in turn also produce electric and magnetic fields. This fact leads to a rich array of properties of the plasma state. A basic knowledge of mathematics and physics is preferable to appreciate fully this text. The author uses examples throughout, many taken from astrophysical phenomena, to explain concepts. In addition, problem sets at the end of each chapter will serve to reinforce key points.
