	An electric guitar pickup does produce an output that is
porportional to the distance of the string to the pickup, but that is only
in a perpendicular plane to the pole of the magnet.

	Actually the output is the voltage produced by differential flux
which in turn is produced by moving a wire through a variable magnetic
field. at the end of each swing the flux is highest, and in the middle of
each swing the flux is at its lowest. (relative to the free flux in the wire
when motionless.)
