Question

How does a Magnetohydrodynamic drive work?

Answer 1

Hint: Magneto Hydrodynamic initiatives work by giving an electric flow through a liquid within the sight of a magnetic field. Solid magnetic fields would require superconducting magnets, which require costly and massive cooling.

Complete step by step answer:
A magnetohydrodynamic drive or MHD quickening agent is a technique for impelling vehicles utilizing just electric and magnetic fields with no moving parts, quickening an electrically conductive fuel (fluid or gas) with magnetohydrodynamics. The liquid is coordinated to the back and as a response, the vehicle accelerates forward. The main examinations inspecting MHD in the field of marine impetus go back to the mid-1960s. Scarcely any huge scope working models have been worked, as marine MHD impetus stays unfeasible because of its low productivity, restricted by the low electrical conductivity of seawater. Expanding flow thickness is restricted by Joule warming and water electrolysis in the region of cathodes, and expanding the magnetic field strength is restricted by the cost, size and weight (just as innovative constraints) of electromagnets and the force accessible to take care of them.
MagnetoHydrodynamic drives are actually explored for equally maritime ships and for spacecraft.
For a ship there is a cylinder running the length of the ship through which ocean water streams. An electric flow is gone through the salt water which is electrically conductive. A solid magnetic field is applied to the water which is at right points to the electric flow. The magnetic field and the electric field interface to apply a power to the water which launches it from the back of the ship.
The benefits of Magneto Hydrodynamic drives are that they have no propellers of other moving parts. They are a lot calmer therefore.
The issue with Magneto Hydrodynamic drives is that they require a generator to create the electric flow which should be driven by a motor or reactor of some sort.

Note:
For the situation of shuttle plasma would supplant the ocean water as the leading fuel. With current innovations Magneto Hydrodynamic drives are more costly and more slow than ordinary impetus frameworks. Innovative advances are needed to make it savvier.
