I found the following KeelyNet reference to Sprain's motor.
You will notice that he is referred to as Paul Harry Sprain,
not Harry Paul Sprain as in the Wiki article and the patent.
Sprain seems to be a remarkably uncommon name. It is probably
a corruption of Strain. 8-)
It would appear that the Achilles heel of magnetic
motors in general is that they are using up energy
stored in the magnets in the form of negative entropy
- in other words in the parallel orientation of the
basic units of magnetism, whatever these may be.
For people who have a naturally
them, how funny that the boring reasonable guys on this list
are the pro-CF people ;)

It's even better than the inventor thinks:

Paul is often a little sloppy with his terminology. He forgets to use
the proper units. The pulse duration is not .028 ms, it's .028 s.
Damn, I didn't finish the post. Why does the brain degrade so quickly

Surprisingly to many, this is not so. When a scientist's name reaches

that usage it is no longer capitalized. This non-capitalization rule is

Wouldn't it be relatively trivial to close the loop on this one -
instead of having his $10k torque measurer, why not stick a (cheaper)
generator on the shaft feeding a capacitor smoothed power supply for
the electromagnet

Of course, the speed is load dependent also, the vid I posted shows the
rotor under load. It spins much faster freewheeling. I think I have an
image of the axial generator somewhere. I load that up directly.

What is the channel two waveform? It looks like the voltage across a
current sampling resistor in series with the solenoid. What is the
value of
the sampling resistor?

Just curious as to the calibration/div for the current probe used on

See the post to George on the probe specs. Does that answer your

Terry,
Yes, thank you. However, the CH2 Mean measurement of 71.3mv isn't accurate
because it appears to be 200mv! I assume the probe was set at 0-10A with
an output of 10mv/Amp, this makes the input current measurement on CH2 to be
2A Mean.
The CH1 voltage measurement seems to indicate

George: I cannot tell from the picture the range to which the
current probe is set. If it is the 10 Amp range , then the 100 mv/amp
signal would give an energy per pulse from the scope waveforms
essentially equal to your calculation of 1.1 Joules

Hi Terry,
Let's examine the workings of the Sprain Mag Motor
in Carnot cycle terms.
With reference to the diagram at:
http://hyperphysics.phy-astr.gsu.edu/hbase/thermo/carnot.html
the conventional Carnot cycle takes the following clockwise path.
Isothermal expansion
Adiabatic expansion
I notice that there is an interesting article
in Wiki on Harry Paul Sprain's magnetic motor.

I saw convincing evidence of 6 Newton-meters produced by 3.2
