But that is not true if you put a negligible load to it. By itself, the voltage induced should only depend on the change in magnetic flux, not the resistance - only when you hook up a load to it, will the voltage be reduced in accordance with the resistance of the body which provides an.internal resistance of the body as a current source. But for our electrocution thought experiment, it is sufficient to argue that without load, the voltage will be the same as in the wire, because then it follows that there is no voltage difference and hence no current. Since for a moving object in a constant magnetic field
Electomotive force = Area swept per time * magnetic field
This should hold
