Electromagnetic buoyancy

{{Short description|Electromagnetic effect that makes particles rise}}

Electromagnetic buoyancy (EMB) is a force that opposes the Lorentz force during electromagnetic phoresis of small particles or droplets in an aqueous medium. It is analogous to the ordinary effect of buoyancy observed when objects float in liquid under the influence of gravity.{{Cite journal|last=Kolin|first=Alexander|date=1953|title=An Electromagnetokinetic Phenomenon Involving Migration of Neutral Particles|jstor=1679809|journal=Science|volume=117|issue=3032|pages=134–137|doi=10.1126/science.117.3032.134|pmid=17831169|bibcode=1953Sci...117..134K}} Though this force is still being researched, it has been clearly observed in experimental procedures.{{Cite journal|last1=Namba|first1=Makoto|last2=Watarai|first2=Hitoshi|last3=Takeuchi|first3=Tetsuya|date=2000|title=Migration of Polystyrene Microparticles in Aqueous Media Caused by Electromagnetic Buoyancy|url=https://www.jstage.jst.go.jp/article/analsci/16/1/16_1_5/_article|journal=Analytical Sciences|volume=16|issue=1|pages=5–9|doi=10.2116/analsci.16.5|doi-access=}}
