Are magnetohydrodynamic engines real?

Are magnetohydrodynamic engines real?

Here is the cool part: This magnetohydrodynamic drive, which turns water into a sort of rotor, is a real thing. (Although technically in the book version this drive is something other than magnetohydrodynamic. Quibbles.) Well, when you put a positive and negative plate in salt water, it produces an electric field.

How does a magnetohydrodynamic drive work?

A magnetohydrodynamic drive or MHD accelerator is a method for propelling vehicles using only electric and magnetic fields with no moving parts, accelerating an electrically conductive propellant (liquid or gas) with magnetohydrodynamics.

What is Magneto aerodynamics?

Magneto-aerodynamics is truly an interdisciplinary endeavor; the interacting physical phenomena require the interplay of aerodynamics, electromagnetics, chemical physics, and quantum physics to describe ionized gas flow in the presence of electromagnetic fields [10], [11], [12].

What is a caterpillar on a submarine?

In the 1990 thriller “The Hunt for Red October,” the Russian Navy fielded a new submarine with a “caterpillar drive” that used nuclear-produced electricity to create magnetic fields that pushed water to the rear of the vessel, propelling it forward without any moving parts in the drive line.

Do submarines have caterpillar drives?

Is Salt Water magnetic?

Salt water has less of an effect on magnets placed near it than regular water because the salt lowers the water’s dimagnetism. A magnet placed near or in salt water will continue to attract magnetic objects in the water.

What is the principle of MHD power generation?

The principal of MHD power generation is based on Faraday’s law of electromagnetic induction, which states that when a conductor and a magnetic field moves relative to each other, then the voltage is induced in the conductor, which results in the flow of current across the terminals.

What is magnetohydrodynamic effect MRI?

Blood flow in high static magnetic fields induces elevated voltages that contaminate the ECG signal which is recorded simultaneously during MRI scans for synchronization purposes. This is known as the magnetohydrodynamic (MHD) effect, it increases the amplitude of the T wave, thus hindering correct R peak detection.
