Electric propulsion methods include:[10]

  • Electrothermal thrusters, wherein electromagnetic fields are used to generate a plasma to increase the heat of the bulk propellant, the thermal energy imparted to the propellant gas is then converted into kinetic energy by a nozzle of either physical material construction or by magnetic means;[citation needed]
    • Arcjets using DC current or microwaves
    • Helicon double-layer thrusters
    • Resistojets
