  2. Electromagnetic propulsion - Wikipedia

    en.wikipedia.org/wiki/Electromagnetic_propulsion

    Electromagnetic propulsion (EMP) is the principle of accelerating an object by the utilization of a flowing electrical current and magnetic fields. The electrical current is used to either create an opposing magnetic field, or to charge a field, which can then be repelled.

  3. Magnetohydrodynamic drive - Wikipedia

    en.wikipedia.org/wiki/Magnetohydrodynamic_drive

    Plasma propulsion engines using magnetohydrodynamics for space exploration have also been actively studied as such electromagnetic propulsion offers high thrust and high specific impulse at the same time, and the propellant would last much longer than in chemical rockets. [14]

  4. Magnetohydrodynamic generator - Wikipedia

    en.wikipedia.org/wiki/Magnetohydrodynamic_generator

    A magnetohydrodynamic generator (MHD generator) is a magnetohydrodynamic converter that transforms thermal energy and kinetic energy directly into electricity.An MHD generator, like a conventional generator, relies on moving a conductor through a magnetic field to generate electric current.

  5. Excitation (magnetic) - Wikipedia

    en.wikipedia.org/wiki/Excitation_(magnetic)

    Except for permanent magnet generators, a generator produces output voltage proportional to the magnetic flux, which is the sum of flux from the magnetization of the structure and the flux proportional to the field produced by the excitation current.

  6. Mass driver - Wikipedia

    en.wikipedia.org/wiki/Mass_driver

    A mass driver or electromagnetic catapult is a proposed method of non-rocket spacelaunch which would use a linear motor to accelerate and catapult payloads up to high speeds. Existing and proposed mass drivers use coils of wire energized by electricity to make electromagnets , though a rotary mass driver has also been proposed. [ 1 ]

  7. EmDrive - Wikipedia

    en.wikipedia.org/wiki/EmDrive

    All designs for electromagnetic propulsion operate on the principle of reaction mass. A hypothetical drive which did not expel propellant in order to produce a reaction force , providing thrust while being a closed system with no external interaction, would be a reactionless drive , violating the conservation of momentum and Newton's third law ...

  8. Magnetoplasmadynamic thruster - Wikipedia

    en.wikipedia.org/wiki/Magnetoplasmadynamic_thruster

    An MPD thruster during test firing. A magnetoplasmadynamic (MPD) thruster (MPDT) is a form of electrically powered spacecraft propulsion which uses the Lorentz force (the force on a charged particle by an electromagnetic field) to generate thrust.

  9. Electromagnetism - Wikipedia

    en.wikipedia.org/wiki/Electromagnetism

    The electromagnetic force is one of the four fundamental forces of nature. It is the dominant force in the interactions of atoms and molecules. Electromagnetism can be thought of as a combination of electrostatics and magnetism, which are distinct but closely intertwined phenomena. Electromagnetic forces occur between any two charged particles.
