The magnetosphere of the Earth may be characterized by an electron number density n.=1011 m³ a temperature T=1100 K and time between collisions with neutral particles is īn = 10–6 s. Assume that the radius of the magnetosphere is comparable to the radius of the Earth (that is, 6.38×106 m). a) Calculate the Debye length Ap in meters for the magnetosphere. Is the first criterion of a plasma satisfied? b) Calculate the plasma parameter A for the magnetosphere. Is the second criterion of a plasma satisfied? c) Calculate the plasma angular frequency wp in radians per second of the magnetosphere. Is the third criterion of a plasma satisfied?
