Magnetohydrodynamic drive

A Magnetohydrodynamic (MHD) drive is a method of propulsion that uses the principles of magnetohydrodynamics, which is the study of the behavior of electrically conducting fluids in the presence of magnetic fields. In an MHD system, a conducting fluid (such as plasma, seawater, or liquid metals) is propelled by electromagnetic forces generated by the interaction between the fluid's motion and an external magnetic field.
