I thought that coils were used in transformers to affect other coils nearby via an electromagnetic field. That this is done in order to transform the power up or down. Like low voltage to high and vice versa. Also, same regard with current.
So how is it that a single coil(the transformer coil) can do what it is doing in this video? How can it be upscaling the current that is directly attached to it? This isn't occuring via induction, right? There's physical contact!

How can it not be burned up just as is the items attached to it's wiring? Isn't the wires coming out of the transformer connected in series with it? Why would the current be any different at the exterior point than at any other point in the wire along the coil(inside the transformer)?
Why doesn't hooking up the wires(coil) of this single transformer directly to a power source cause an explosion? There isn't any resistance to infinite current since there isn't a resistor attached to an end of the circuit, right?
It's just so confusing seeing one coil do what it's doing. I thought you needed two coils for transformers to work. That one coil would have a greater number of turns and the other lesser depending on which way you wanted to power to scale....
