The net mechanical gain could possibly compensate the thermal losses
of a simple demagnetizer section. I'll assume there's a few
microwatts left over to keep a flywheel slowly turning against air
friction. Very cool if true!!! Aaaaaaaand, if that works, then
perhaps we can build a version resembling a 'parametric
oscillator.' Add a battery! This would resemble a battery-powered
ferrite coil (although a constant-current source would be more
appropriate.) As the whirling supermagnets passed by, the
demagnetization would produce tiny alternating pulses of back-EMF.
Then the battery would re-magnetize the ferrite after a small delay.

That one I'm not so sure about (except as existence-proof from
steorn!) But my earlier one is pretty simple, so probably the only
challenge would be to make it run for hours rather than seconds.

Only if shown to be untrue by experiment.

By "stressing" a permanent magnet (i.e., applying opposing magnetization),
you drive its B-H curve slightly backwards. If you push it past the
coercive force Hc, you'll demagnetize it. Fortunately, this takes an awful
lot of magnetization (ca. 1MA/m). For normal operating levels, you only
push the magnet a little way back along the B-H curve. Because it's quite
square, the drop in remanence (field strength) is small, and after an
initial burn-in at full load, it will remain quite the same for the rest of
its operating life.

Bwuahahahahahahahahaahahahaha!

What part of the word "permanent" do you not understand?

Sam My Boat is so small.(just a barrel) Still wind was first used and
every motor has a fly wheel. Flywheel can store energy. They are
protential energy and go round and round I like that feature TreBert

Just the same you had made a blanket statement that was easy to punch holes in.
On top of that there are electric motors that do not have iron armatures precisely
to reduce the rotating mass. Also the blades of high speed turbines are very
decidedly not heavy, simply because they would come off at the high rotational
rates (in excess of 100,000 rpm). Care to join the us readers?
