Consider the following situation; A large magnet rotates in the vicinity of
a large coil, so that the magnetic lines of force intersect the coil at
right angles at some point in the revolution. If the magnet is on the side
of the coil a sine wave output can be obtained form the coil. When the coil
is shorted or powers a load the rotating magnet experiences a mechanical
resistive force due to lenz law. The current established in the coil
produces a magnetic field that opposes the relative movement of the
rotating magnet. Now suppose for some reason we wanted to cancel the
induced currents in the coil by sending an ac signal 180 degrees out of
phase with that of the induced. Since the voltages would cancel out zero
current draw would issue from this hypothetical cancellation generator,and
therefore zero power would be consumed. Does anyone disagree with this
assessment.
