Yes, my body has a higher resistance than the wire, of course. But in the formula for the voltage induced by a magnetic field, the resistance of the material doesn't appear! You can check...
From some of your previous posts, you apparently have some physics knowledge and you know that basic formulas do not take into account various variables and zeros most often do not work. In this case the wire is assumed to be zero resistance. Basically, the current is equivalent throughout the circuit and the voltage is distributed along the loads per Ohm's law and if you really expand the formula the zero resistance will rear it's ugly head. Ohm's law is a basic formula that if zero resistance is inserted you will have infinite current. There is also impedance to be considered and any circuit with changing voltage that will induce reverse current because the changing voltage will create it's own magnetic field which will induce reverse voltage.
(and resistance is inherently within the formula as E=I*R Where E->Voltage I->Current R->Resistance)
You make people miserable and there's nothing they can do about it, just like god.
