In #MESExperiments 55 I once again demonstrate Faraday's Paradox, this time showing that rotating a strong magnet with a drill about it's polar axis doesn't move individual football shaped magnets. Each magnet is placed on a polished low friction glass mirror surface, and the football shape allows the magnets to freely rotate. Moving the strong magnet attached to the drill laterally easily moves the magnets, but rotating it barely even nudges the smaller magnets. This suggests that the magnetic field does not rotate about a spinning magnet.
