  1. Excellent video! However, a small error at 5:41: you say that there are still gaps with 3-phase power, where in fact there are NO gaps. The total amount of power supplied by 3-phase electricity into a balanced load is exactly constant. So adding more phases would not be an improvement.

  2. It seems the video is showing *current*, not voltage. Current is induced by a change in magentic flux, which is zero at the poles and higest between poles.

  3. 3:30 "It is too fast for the eye to see" No, you can not see the incandescent light switch on and off with slow-motion because the temperature of the filament only fluctuates a little bit. It doesn't drop below the temperature where it stops producing light in the time that there is no current flowing through it.
