Main Question or Discussion Point
I saw this and thought it was interesting. If one can get beyond the pretentious music, super annoying robotic narration and ignore the completely off the wall theory discussion there remains a reasonably well documented experiment. The measurement shows the B field about a conducting cylinder due to an axial current is greatly increased by rotating the cylinder. I would think this additional B is due to a helical component in the drift velocity of the rotating electrons. Anyone familiar with how to compute this addition B?
