What is Mhd: Definition and 21 Discussions

Mohamed Sylla (born 10 September 1994), better known by his stage name MHD, is a French rapper from Paris, who is known for blending trap music with music of West Africa; a genre he coined as "Afro Trap". He was previously part of the rap collective 1.9 Réseaux.
Born in Vendée to a family of West African extraction, MHD began his career as a rapper in Paris at the age of 18. He found success in the mid-2010s through material he published on social media (notably music videos on YouTube) and in 2016 released his debut album MHD, which sold more than 200,000 copies in 6 months. He later received international recognition, and toured in Guinea, England, Senegal and Morocco. His second album, titled 19, was released in September 2018.
In January 2019, MHD was arrested by French police and charged with second-degree murder following investigation into a murder case dating back to 2018. Claiming his innocence through his lawyer, he was then remanded in custody for 18 months. Released under supervision, he is currently awaiting trial.

    I Question about magnetohydrodynamics (MHD) for electricity production

    According to the MHD theory, is case of energy production, a magnetic appplying a magnetic field to a moving charge perpendicular to the magnetic field, that could be plasma as well a solution full of ions, and placing two plates, electricity could be produced. Now I have a question, let's say...

    Use of hard drive magnets to build an MHD propulsion ship

    In order to build a small mhd propulsion ship for a physics project, I'm wondering if the magnets we find in hard drives carry enough magnetic field power to function in such an experiment.

    Mystery Voltage: Investigating a Strange Phenomenon in MHD Testing

    So something weird just happened along the way in my experiment, here is a little background of what I'm doing. I have created a roughly 3x5mm inner diameter rectangular shaped channel for MHD liquid testing for one other project of mine, it's a simple conduction type MHD pump where the...

    MHD Generator Performance with Ionised Gas

    As per this wikipedia page, plasma is necessary for functioning of an MHD Generator. But, what I want to know is if just simple ionised gas is used instead of plasma, will the generator perform in the same way? As per my little knowledge of physics, there is no reason that it wouldn't. Because...

    Ideal MHD equilibrium equations

    I have a question about the ideal equilibrium MHD equation: \vec{J} \times \vec{B} = \nabla p where \vec{J} is the current, \vec{B} is the magnetic field, and p is the plasma pressure. Does the magnetic field here represent the total magnetic field (any applied external fields plus...

    Looking for a MHD simulation (Magnito-Hydro-Dynamics)

    I'm looking for a simulator for magnetism and fluid dynamics(with the objective of modeling atmospheric reentry), and was wondering if anyone knew of one(preferably free/open source). If anyone feels like searching(I couldn't find anything) the field is called magnetohydrodynamics. In the...

    MHD equations - confused about derivation

    I am confused about the usual derivation of the ideal magnetohydrodynamic equations, as given for example here: http://theoretical-physics.net/dev/src/fluid-dynamics/mhd.html The problem is that there are a few different "currents" to consider. For example, in the momentum equation, the...

    Question on energy conversion in MHD

    During the astrophyscial MHD class, I got a simple question on conversion of magnetic energy to plasma's kinetic energy and vice versa. When macroscopic magnetic force is exerted on a chunk of conducting fluid, we say work is done by B-field and magnetic potential energy is converted into...

    Are there any people actively doing research in MHD topics these days?

    Are there any people actively doing research in MHD topics these days? It seems like an interesting field, but all the information I've come across only dates as recent as the early 1990's. What happened? :confused:

    What is the explanation for magnetic pinching in plasmas and conductive fluids?

    Can someone give me an intuitive explanation why plasmas or conductive fluids tend to follow magnetic flux lines? E.g. http://en.wikipedia.org/wiki/Magnetohydrodynamics" entry on this says: If I take a stab at a qualitative explanation, is it because magnetic flux lines are equipotential...
