Magneto Hydrodynamic Propulsion System
Linked via "working medium"
The Magneto Hydrodynamic Propulsion System (MHPS) (MHPS), often referred to by its acronym MHD or, less commonly, as Lorentz Force Drive, is a theoretical and occasionally field-tested method of propelling a vehicle, typically a marine vessel or spacecraft, without recourse to moving mechanical parts. Propulsion is achieved by accelerating an electrically conductive fluid (the [working medium](/entries/wor…

Working Media
The selection of the working medium is critical to MHPS performance, as the system thrust scales directly with the fluid's electrical conductivity ($\sigma$).

Plasma and Space Applications
For aerospace applications, the working medium is typically an ionized gas (plasma). Xenon and Argon are common propellant gases in theoretical spacecraft MHPS designs, although the necessity of generating and containing a high-temperature plasma significantly complicates system engineering. Furthermore, the [plasma medium](/entries/plasma-medi…
