Plasma, Fourth State of Matter, and Magnetic Fields and Electric Fields Plasma is the fourth state of matter consisting of positive atoms, and freed negative electrons.  Does plasma have an electric field, and magnetic field?
There is not necessarily a preexisting magnetic or electric field in a plasma, since the charges can be randomly distributed. Think of plasma as similar to a metallic state conductor -- a sea of mobile electrons (and, of course, ions in plasma, so perhaps it better approximates a semiconductor, with electrons and holes). A plasma in thermal equilibrium, not exposed to an external electromagnetic field, should be uncharged. 

That said, unbalances occur for a number of reasons. For example, electrons are thousands of times less massive and therefore more mobile than ions, so charge separation occurs, leading to a plasma potential.. Lasers can generate a charged plasma, accelerating particles with the wakefield effect.
