Work from 2 magnets > 19% output 2

@Low-Q

The goal of this topic is the presentation of replications of the measurement process / experiment.

I do not agree with your interpretations of the information at http://hyperphysics.phy-astr.gsu.edu/Hbase/magnetic/elemag.html .   

Also I do not find your choice of wording to be concise enough to allow for a meaningful response
on my part.

except that

I do not agree with your conclusions.

The link you posted doesn't work.

That link Is working now.  (it's the same old link)

I think you have brought up, good questions.  The ultimate answers to
which, I may have no answers ? 

I apologize that I am distracted these recent days. An old friend is soon to pass on.
He and the family, need a little support at this time.
.........................................

1. Assume I place a magnetic compass at a distance from an electrically energized coil, which is producing
a magnetic force.
At some distance (millimeters m) the compass needle deflects some amount (degrees d).

2. Assume I add an appropriate (magnetically soft and normally un-magnetized) iron core to center of
this energized coil.
At the distance (millimeters m) the compass will now deflect > (degrees d).
              or
the compass needle will now deflect (deflection d), but while compass needle is at
> (millimeters m)

I hope this some kind of a useful answer.

                     best wishes

PS
I wold like to start a new topic, which if specifically for these info s, ideas, and theories,
while leaving this topic to be specifically for actual measurements, and examinations of the methods and devices
of those measurements ?

Sorry to hear about your old friend. It's hard to keep a clear mind in hard times. My best whishes for you, your friend and his family.

Sounds like a good idea you have about the compass. I will do this experiment too. I think I will add a spring to the compass (Just made by a couple of neos), so it is possible to get an indication of the forces from some distance - with and without the iron core.
I will assume the compass will just smash into the iron core at close up measurements. If you don't mind I can post my findings in your new thread.

The new topic is called

                Magnets, motion and measurement

                       floor

[Floor]

Please find the attached file "pasThru 2"

The design and method is given into the public domain.

It requires less work to position the rotating magnet between the
other magnets, than the work which can be done by the rotation.
