I have been trying to understand the physics of this and it just does not compute in my head. I would like to say it is bogus but I have had coils that would not glow evenly or have hot spots and then strum them and voila the hot spots are gone and they glow evenly. But I think about it and I can't see how lightly strumming a coil can make any physical difference in the coil in any way what so ever.
Can someone help me make this make sense to me. What does strumming physically do to the coil to make it behave differently?
