Simple Experiment: Extraction of Energy from Permanent Magnets

[dieter]

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.

The permanent magnet dynamo also produces more power per volume with stronger magnets. This doesn't make it more effective or even overunity.

SO IF WE WANT TO CREATE A MAGNETIC FORCE FIELD OF 100 MILLI TESLA.,
WE CAN JUST GET A MAGNET TO DO THAT
STRAIGHT UP. WE DO NOT HAVE TO WIND A COIL, WE DO NOT HAVE TO SPEND ANY
ELECTRICAL ENERGY TO CREATE THAT THROUGH AN ELECTROMAGNET.. WELL FROM
A COCKROACH POINT OF VIEW ONLY A DUUFUS  WILL NOT BE ABLE TO GET THE GIST OF THAT..

You are not going to get OU because you have superconductive coils.  Let's get real and talk about a simple experiment that anybody can do in the real world.

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.

I am going to assume that you can measure velocity with a regular camera or a cell phone camera by doing frame-by-frame displacement analysis.  Measuring velocity is such a critical measurement that 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.)

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

To think I've just posted a link to this a few posts back.

Milehigh, you made the following statement:

Now, it's a mistake to assume that the pulse energy will be the same for the small magnet and for the large magnet.  Chances are the pulse energy will be smaller for the case of the large magnet.

Then in the same post you made this statement:

The conclusion is that the magnets in both cases are as dead as proverbial door nails and all of the energy for both cases was provided by the pulser circuit.

Those two statements appear to me to be contradicting one another.  If the magnets are dead as door nails then why would the pulsing current be different?  And why would the current be less for the more powerful magnet?

Respectfully,

The pulsing current will be different because the magnetic environment is different between the two setups.  That doesn't mean the magnets are doing anything special, it means the coils will experience different levels of changing flux as they are repulsed away from the two different magnets.  In the case of the more powerful magnet, when the coil jumps away from the magnet, it will see a greater amount of changing flux with respect to time and therefore there will be more counter-EMF induced in the coil which will reduce the current flow more than for the case for the weaker magnet.
