Simple Experiment: Extraction of Energy from Permanent Magnets

[MileHigh]

Quote of quote:

Chances are the pulse energy will be smaller for the case of the large magnet.

So by that statement milehigh does support the deconstruction of the law of energy conservation, basicly saying what I said: the stronger the PM, the lower the coils consumption. Really surprising to hear that from Milehigh.

Thanks everybody for your interest and contributions.

No, you are coming to an incorrect conclusion.  See my previous post to Carroll.  You are failing to look at this experiment as an exercise in analyzing power or energy transfer dynamics in a system as you change one variable.  It is somewhat akin to impedance matching.  With the stronger magnet the system is more amenable to taking the supplied power from the pulse circuit and turning it into kinetic energy.  In essence, you have a more efficient motor with a more powerful magnet.  "Efficiency" means looking at waste heat energy versus useful output energy.  All discussions pertaining to issues like this that don't discuss waste heat energy and account for it are failing discussions.  What is the extreme limit?  If there is no magnet in place and you pulse the coil then it does not move and 100% of the pulser energy becomes waste heat energy.  Presumably, if you start from a very weak magnet and slowly increase the strength of the magnet the coil will get more and more kinetic energy from the pulser.  So you start with 0% efficiency with respect to kinetic energy as a percentage of pulser energy and that efficiency presumably increases as the magnet gets stronger.  Is there some limit to this because of other effects not being accounted for?  Perhaps there is, I don't know.

If a coil has zero resistance then once switched off (at correct time) you should be able collect back most of the input from the Inductive discharge.
The free lunch comes from the magnetic field created by the coil during its on time.

Taken from your quote above "I am almost shocked that I have never seen someone do it around here by optical means"

What do you think I did here? : https://www.youtube.com/watch?v=-zdfBbDarQw

I don't understand what you are saying.

There is no optical speed measurement in the clip, "Mostly Magnet Motor Super build test 3."

Don't even start with the attitude, switch it off right now.  Beyond that, I haven't watched your clips for the past three or four years.

@Zephir, by Dynamo (the farraday disc, homopolar) you mean the Magneto.
However, in conventional direct PM Generators the Lenz drag works against the input force. In a magnet motor the Lenz drag works against the PM, but can be weaker due to the recursive decay.


Speaking of which, there is only one recursion of induction, as the magnet will not mirror the secondary field.


In any way, I'd like to remind you of the essence of induction: when a field of an external magnet decreases in strength (because it's moving away) then the coil will attract the magnet (Lenz Drag).


But currently the pulse current does repell. So the induced current is opposite the pulsed current, increasing the resistance, decreasing the potential diffrence in voltage, heck, may even charge the battery.


And even so, the stronger magnet is repelled further away. In fact if a stronger magnet flies faster, the pulse may be shorter as well.


Sometimes these things are like glitches.

Btw, Zephir, quote:


"The stronger magnet also induces stronger back electromotive force within the coil. That is, you would need to use higher voltage at the input for to achieve the same increase of current.."


That is true, but even with a lower current flowing, the stronger magnet still flies further away. And that's exactly the point. Less input, more output.

I see!... anyone else having a problem understanding my quote below?

That's correct!  no speed measurement in that clip.
The clip is about the part you wrote (bold) below.

I am almost shocked that I have never seen someone do it around here by optical means.  (Or you can flip the whole experiment on its side and measure the maximum height the pulsed coil jumps against gravity).
