This is my last version of part one of the "
magnets Motionand Measurement"
                     book.

I not going to make any further revisions to this "the part 1". 
I am for the present satisfied with all of the corrections of my
wonderful mistakes and missunderstandings (in these contexts).

Anyone may (if they find these explanations satifactory)
redistribute those pages.

Please find the attached file

It is a pleasure to share my latest project where magnets, motion and measurement are coming together
in a DIY project. The Donut Motor is powered by a 3V lithium cell with a 235 mAh capacity.
The pulse motor runs for 2 years on a single coin cell with a current of 13 uA. It is great to enter my
lab and see this motor running day after day. The investigation is going on to get the current as low I can.
Here is the video of the project.

What is it, that you hope to demonstrate with your motor project ?

@Floor, I was hoping the video gives that answer in a practical way. Reading your opening of this thread and your definition of the topic, I anticipate with an apparatus where energy, work, force, power and the methods of their measurement can be in discussion. It is easy to stay in abstractions. I learned a lot about magnets and their interactions by building this pulse motor.
I hope you, and more people at this forum, start building the Donut motor. Maybe we come to a point that conventional scientific descriptions cannot explain the behavior, why this machine, in the near future, can run without any explainable input. That is in short what I hope to demonstrate with my motor project. Any reaction at this project from your side is welcome.

@LabDeSyn

I would prefer it if you will start a seperate topic which is for your Doughnut motor.

In a very general way, almost any thing can be considered in a context of m m and m.

And while a pulse motor is surly more so conected to this topic than... say electro chemistry or
magnetic recording tape, it still remains as essentially off topic.
