Great!
now you should see if you are getting more (or less) power out than
you put in to make the motor spin.

Actually, that sounds like a better project for you! 8^)
I lack your equipment and practical knowledge.
Based on the results of this experiment there are far better places
to apply my limited equipment, practical knowledge, money and time.
It can't be even close, as far as mechanical energy. The input is
almost all going to heat.
Marinov's force derived free energy
should
all show up in the form of torque, i.e. mechanical energy. I see
no
reason whatsoever to expect excess energy, or even to have to draw
on
Marinov's longitudinal force to explain the operation of the motor.
I am unfamiliar with Marinov's force. Even if magnetic hyestersis
is the
best explanation for the increased rotation why does the coil heat up?
The nichrome coil is a resistor being fed a large current. P = i^2 *
R. Why does a hot plate heat up? Why does an iron heat up, a hair
dryer or an electric space heater? If you are wondering why the coil
heated up visibly for the ordinary steel bearings and not the
stainless bearings, the reason is that with the rotating motor I
could leave the power on long enough for the coil to heat up. The
stainless steel motor shut down rotation very fast so I had to cut
off the power fast to prevent welding. Part of the art of doing this
experiment is keeping the current low enough that the stainless steel
will not weld. The stainless steel bearings are very different from
ordinary bearings. Stainless notoriously welds very much better,
because the surface doesn't quickly pacify by oxidation like ordinary
steel. The art of this experiment is getting things to run without
destroying the stainless bearings by welding. This means running at
the lowest possible current that gets clear results.
One of the best practical things I learned is powdered graphite
lubricant, which comes in little tubes that look like toothpaste or
ointment tubes, greatly reduces welding and surface destruction due
to arcing, while having little effect on the resistance of the
bearing. It also had a very positive effect on my locks, which were
long overdue for lubricating, so something practical came of this
experiment! 8^)
If the system were generating electricity and adding it to the
supplied
current this would cause the coil to heat up.
The magnetic hysteresis explanation looks far more credible, and
definitely more conventional to me.
I have far better designs to test for non-conservative forces, if I
can ever get around to implementing them.
