One possible explanation that the test coil stays still, is because the micro-helices within the metal of the coil itself, are not strong enough to break out of the coil, due to the earth's own magnetic lines of force that are pushing back onto the coil, in the counterclockwise position.
My best guess is that rotating the base changes the magnetic field due to the base's material/wiring. A much easier test would be to have 2 LEDs also in parallel but in opposite direction. Then without moving anything but a switch, change the current direction from one to another.

ReplyDeleteHave you tried using a pulsed current?

It is interesting the micro-helices. I do not know this. Can you explain more?
DeleteIt is not the earth's field because without the magnets, the test coil does not rotate. I will show a video of this next.
I did not use pulsed current.
Thanks Samuel

Yes. Someone has suggested this.
