Last I knew, a magnetic field has to be moving through/around a coil of wire in order to generate electricity, AC electricity.
That's why generator armatures rotate, driven mostly by gasoline engines.
With the wires going to the spark plugs, there is no "coil", and there is no movement of the magnet.
You can try it, but don't expect anything.
EXACTLY RIGHT. One more internet hoax. And even if the magnet was moving, the voltage generated in a single wire would not possibly light up an LED. That's why generators have a coil of wire. And of course, what possible contribution could the spark plugs be making??? Pure sham window dressing.
