a: Plasma ~
b: a perfect conductor


" A plasma is like a perfect conductor, in that it shields out static electric fields;the charges within the plasma rearrange themselves so that the E -field is zero except within approximately one Debye length of the edges of the plasma. De-bye shielding is effective only if there is no magnetic field in the plasma; in the presence of a B field the shielding is less complete, as we shall see "
