When the piece of wire is charge separated, we will find electrons bunched up, so to speak, at the negative terminal and protons at the positive terminal. If we connect an external resistive load to the wire outside the core, we will then see a current flow that will be called one of two types depending on one's view.
absolutely! im with you there.. years ago messing with AV plug and charging a cap via 1 wire from 1 lead of the sec of a small hv 1200v neon transformer is where i came to that conclusion. so i ask this...
do you believe that on the neg end of that sec(at the time that the ac out is at peak neg), 1200v, that the bunched up neg charge would release some into that av plug to charge up that cap, 'as if it were just an extension of that sec winding'? lets say even further, that sec hv lead wire coming out of that hv transformer, would it also contain bunched up electrons? further more, extend that wire to a greater length, would there be bunched up electrons in that extended wire also?
One type is conventional current flow where the reference is the flow of positive charge from the positive terminal to the negative. In semiconductors this is called 'hole flow'.
"hole flow" definition of a 'hole' is a valence band electron missing from an atom, of which makes that atom positively charged. are you saying that the hole itself flows or that the atom itself flows?
when an atom is normal, equal amount of electrons and protons give that atom a neutral charge. remove an electron and the atom becomes positively charged. thus in my thinking, the pos end of that wire is just filled with atoms in the wire structure that have a pos charge and nothing more. just missing electrons on that pos end.
if you are talking about 'ions', atoms with a non neutral charge, moving through an electrolyte, then we are not talking about wires.
If the load however is placed in the hole of the toroid along with the wire, there is equal charge separation in both the wire and the load with the result being no current flow no matter which type of reference you choose.
thats understandable. as both the load and the wire of the loop are induced equally. but, as i believe you said earlier, i think, you can measure the top of the loop and the bottom, each out of the window of the core, and see voltage, similarly like just 2 wires connected at top and connected at bottom, where in our case the load is like one of the wires. so there should be say bunched up electrons at one connection of the loop out one side of the window, and pos charge(atoms with holes) at the connection on the other side of the window. if so, then you did have current flow to get those electrons to one end of that loop that is outside of that end of the window. maybe not a lo but current flow did happen both in the wire and the load of the loop.
