>>14212072no, he didn't say that kirchhoff's law don't hold you idiot, he's just saying that the lumped component approximation makes no sense if a magnetic field is included in the system.
Say you have a standard voltage generator of amplitude E + resistor a resistor connected to it with wires the current I should be defined by ohm's law, i.e V = RI, and since kirchoff's law holds here, E -V = 0 therfore E = V therefore E = R* I
But if you start putting a magnet in the center of the wires and move it another current will be generated due to the magnetic fucking flux, I isn't the same anymore as there is a magnetic contribution and therefore you can't say E-V = 0 but something else.
ElectroBOOM just countered the argument by saying "yeh well then we add a transformer to take into account that effect, which makes sense, but Lewin is a fucking physicist, so he only works with R,L and C.
