No way could a wire merely passing the starter motor get sufficient
power induced into it to generate a delta-V of say 20V across the
length of wire that passes the starter motor.
How much of a collapsing field would it take to generate say 20V
across say 6" of wire?
And remember, the battery is still connected, so one would be inducing
into a pretty low impedance node.
