This is in contrast with ion thruster engines, which generate thrust through extracting an ion current from the plasma source, which is then accelerated to high velocities using grids/ anodes. It is ejected from the engine. They can be classified roughly into five groups, the first three of which are relevant to the present topic and will be discussed in turn. A magnetic nozzle accelerates the hot plasma to produce useful thrust. Many plasma rockets have been under devel- . Indeed, the specific impulse of the electric propulsion system is, in most cases, a mission-dependent parameter.

Step 3--Electrons impact the propellant atoms to create ions (shown in blue). particles accelerated by electric and magnetic fields, these engines expand the range of rocket propulsion far beyond the limits of the chemical rocket, with a fuel consumption very much lower. Plasma is the building block for all types of electric propulsion, where electric and/or magnetic fields are used to push on the electrically charged ions and electrons to provide thrust. This is in contrast to ion thruster search engines, which generates forced through extracting a ion current from plasma source, that's then accelerated to high velocities using grids/anodes. Even it gives less thrust than conventional rockets, they are able to operate at higher efficiencies for longer periods of time. Plasma is the fourth state of matter and is characterized by an electrically neutral gas, that is, all positive and negative charges in the gas have a combined net charge of zero. There are many techniques to achieve this result : the VASIMR motor or the Hall effect motors are examples of plasma motors. Also a magnetic nozzle directs the plasma in the desired direction to produce a thrust.
