Editing Magnetohydrodynamics (section)

== History ==
The MHD description of electrically conducting fluids was first developed by [[Hannes Alfvén]] in a 1942 paper published in [[Nature (journal)|''Nature'']] titled "Existence of Electromagnetic–Hydrodynamic Waves" which outlined his discovery of what are now referred to as ''[[Alfvén wave]]s''.<ref>{{cite journal | last1 = Alfvén | first1 = H | year = 1942 | title = Existence of Electromagnetic-Hydrodynamic Waves | bibcode=1942Natur.150..405A | journal = Nature | volume = 150 | issue = 3805| pages = 405–406 | doi=10.1038/150405d0| s2cid = 4072220 }}</ref><ref>{{cite journal |last1=Fälthammar |first1=Carl-Gunne |title=The discovery of magnetohydrodynamic waves |journal=Journal of Atmospheric and Solar-Terrestrial Physics |date=October 2007 |volume=69 |issue=14 |pages=1604–1608 |doi=10.1016/j.jastp.2006.08.021|bibcode=2007JASTP..69.1604F }}</ref> Alfvén initially referred to these waves as "electromagnetic–hydrodynamic waves"; however, in a later paper he noted, "As the term 'electromagnetic–hydrodynamic waves' is somewhat complicated, it may be convenient to call this phenomenon 'magneto–hydrodynamic' waves."<ref name="alfven43">{{cite journal|last1=Alfvén|first1=Hannes|title=On the Existence of Electromagnetic-Hydrodynamic Waves|journal=Arkiv för matematik, astronomi och fysik|date=1943|volume=29B(2)|pages=1–7|url=https://archive.org/download/MagnetohydrodynamicWavesAlfven1943/Magnetohydrodynamic%20waves%20-%20Alfven%201943.pdf}}</ref>
