In #MESExperiments 36 I further demonstrate Faraday's Paradox, this time using Ferrofluid and showing that a magnet rotating about its polar axis has no effect on the fluid. I also perform additional experiments using iron filings using more complex patterns to show that they are still not affected by the rotating magnet. This is a follow-up to Experiment 35 which I performed similar experiments but with the magnet at a distance away from the iron filings. According to Michael Faraday's theory on magnetism, the magnetic field "lines of force" should be moving and cutting through the iron filings and they thus should experience an electromotive force (EMF), which paradoxically don't. This suggests the magnetic field does not rotate. Further information on Faraday's Paradox as well as FractalWoman's magnetic isopotentials explanation for it can be seen in the video description of Experiment 35:
