Does this also include the core or magnets?
Magnets and cores are not part of an electrical circuit
...seems like the danger is when you cut all power to the inductor/coils(while the coils/windings are charged). This releases like a burst of current?
This is well known it is called back EMF but is nothing to do with the problem here because a triac only turns off when the voltage across it is close to zero. It contributes to the out of phase current and voltage but again that is not the problem.
So could you say that metal or ferrite cores or magnets have an influence on the circuit then? Wrapping a core with copper winding (depending on how many turns, etc..)increases it's power or output (or like a transformer can decrease as well) ? Sorry for these questions Mike :) ...Inductance was the one thing I had a hard time grasping in electronics (Capacitance & Impedance...was much easier for me to understand). I understand your second point.
Also, if you have a charged coil, you shouldn't touch it with your hands, right? Is this because by touching the coil you're creating impedance?
Thanks again Mike
