Magnets, motion and measurement

[ayeaye]

So, ayeaye, we are only doing actually " blah blah "

I prefer to do one thing.

I just actually wrote how to measure, the simplest way. I'm not an expert in measurements in mechanics of course, but i can do it the simplest way. And, there was a use of it, i did calculations that showed that citfta got no overunity, i hope there was a use of it for citfta, and others who do similar experiments.

Measuring many times, well, there are all standard deviations and things. Yes, i can calculate these too. But this is only like, when hand error caused different measurements. The greatest error there comes from the scales i think, and when measuring the same value many times with scales, the error may be systematic, that is, always the same. An error is more random with scales, when measuring different values. The real error of scales can be found like when weighing known weights, but for that there have to be several different weights, finding the greatest error. Partly because of the nature of scales, again, measuring only one value, even when doing that many times, does not do it more reliably.

why does not it work?

Because there is no overunity in that thing.

You may try to replicate my experiment instead  https://archive.org/details/Flcm3 , if you have an old computer fan and an old CD. The drawing explaining why it should work  https://ia800903.us.archive.org/22/items/Flcm4/pmmbp12.jpg . Again, it depends on the shape of the field, it does not work in the Coulumb model, but a real magnetic field differs from that, and when it differs, it should work in theory. As i said, it should be replicated with measuring the peak force, and triggering not dependent on the hand movement. But even when there is overunity, it is likely not enough to overcome friction.

I don't believe that drawing is correct.
I believe that the n and s in a magnet are isolated from each other.
An end on view ,the field curves around and terminates at the middle of the thickness, not at the other pole.

when the energy for pulling the stick is taken from the outside, (electricity, electromagnet) controlled by the hall sensor, the drum rotates.apparently, the energy from rotation and the energy for pulling a magnetic stick are equal.
dead end way?

How to say, this drawing is really not a correct depiction of any magnetic field. It is just to show the concept. It doesn't work with the Coulomb model. Coulomb model is like both poles having a separate spherical, that is symmetric field. But a real magnetic field differs from the Coulomb model. And if the field lines are more parallel to the axis between the poles, then there may be enough asymmetry to enable overunity.
