:)

This topic is for deleted posts under the    "Floors MMM-2 builders board".

Interesting but off topic posts may be moved here by me (floor) 
1. as a courtesy
or
2. just to preserve them. 

They may eventually be deleted by me.

                   Message me here if you wish

Moved by floor from

 O.U. Magnet force shielding 1
« Reply #35 on: August 30, 2021, 09:45:58 PM »


The construction i've sketched should also work ?

A bar magnet should be equivalent to a stack of single magnets.
I have some magnets 100x25x3 mm, and round bar magnets 60x12 mm (or 10 maybe).
I also have a amsll slider with steel balls, which requires almost no force to move.

Maybe i can build something from this...

Thank You for opening this up Floor. 

I just wanted to give this link which displays the question a little clearer than the video linked in the post you snipped.

"Can the speed of magnetic field changes be out ran,  if not directly in the fields, then
within, for example, an iron core / at a molecular level? "

I think the experiment I repeated again last night relates to this. Feel free to delete this if it is off topic.

I clamped 2 iron core transformers with 1 open side (electromagnets) together tightly.  then I flipped polarities of 1 transformer at timed intervals as I measured output to load. I also unclamped them and held a magnet over the electromagnet in stages to physically feel the effects.

I did roughly 50 tests from 1 microsecond between flips to 1 second between flips.

With the power supply set the exact same for all tests, as the flips got real quick, the input wattage went down drastically. When between around  5-30 milliseconds between flips, holding the magnet over the electromagnet results in a slight vibration that is almost undetectable. But also the input power goes down to hundredths of a watt, as opposed to 12 watts when flipping slowly.

I must say though I am unsure if any of my measurements were even close to accurate, because I was watching input power as displayed on my power supply, and I do not think there is any degree of accuracy when changing that quickly.

One thing is for sure though,  the flipping magnetic  fields are greatly reduced the quicker the flippining.  If this is happening because the input wattage drops, effects from the iron core, or because of a nulling of the fields from speed, I am not sure.

But if interested, I can probably get a video of all this if anyone's interested

As before, and of course, how you might best / next proceed is up to you.

For me / others to get maximum benefit from your work...

Document all the rpms and
all of the inputs and outputs,
under several conditions

Write them down.

Do this systematically / follow some order of proceeding
that will make it the easiest way for to you to communicate and
for others to understand what each measurement is of and
what are the conditions under which that measurement was taken.

This can give both, you and we the readers a degree of clarity that otherwise
might never otherwise arise / may be not at all.

i.e. follow it through / finish it out.

I think you are correct.  This demonstrates that speed will affect both the energy input
and the        energy transferred       in a pretty clear way. 

Meet as high a degree of precision as your set up can deliver and I believe it will serve
as at the very least a proof of concept.

             If I am understanding your direction at this point...
i.e. quickness of interactions between physical objects interacting through magnetic fields might give rise to something which is     in effect    a kind of magnetic shielding ?

nice builds, good videos, cool concept..

 best wishes

This requires no spinning or moving parts.  I can flip polarities of an electromagnet very easily and quickly with no moving parts using an H-bridge and ardiuno. I can set the delay between flips from 1 microsecond up.  Measuring should be no problem also with this setup.

I can do this

END OF QUOTE

As soon as you introduce electromagnets you also enter into new complexities.

In pulsing coils (on and off )

ohmic resistance of the coils
magnetic saturation of and permeability of electromagnet core materials
current's lag behind voltage in time
wave forms and resonances that will develop
reluctance and reactance of the coils
capacitance of the coils
Quite a few others...

In short a whole new ball game, while you did not, fully present the last two sets
of interactions in your topic.  There is no clear data #1 and #2  and heading into #3 ?

P.S.  for the above


It's like unpainted furniture,  But still, it has merit.

@ All readers

      Generally / nearly always,  when I move a post here, this is done to maintain the
continuity of one of the topics.  Please do not consider my moving or removing
of any post as a reflection upon, the otherwise merits of or validity of that post.

I apologize. I am trying to understand how to remove posts. Do I copy the post and place them in here and you automatically go delete them? Last couple posts in my magnet assisted thread is very full of links and search links and all wrong language. Hides all the content. Any more explanation as to what I am supposed to do to properly remove is appreciated.

This process is new and not at all well tested.

1. Open two copies of your browser.
2. Login to O.U.
3. in your topic   there     quote the entire post you wish to remove.
4. highlight it and then cut it (controll x).
5 switch to the other browser and navigate   here  to the dust bin.
6. click on    reply    below the latest post in the dust bin.
7 paste the quote (controll v).


Good ordering in regard to which is attached to what does not matter here.

The whole affair is a courtesy any way / for the record kind of thing
and its is all your own call.

8. Post in your topic.  Floor please delete messages x, y. z...
                         example this very message is
https://overunity.com/19040/permanent-magnet-assisted-motor-coil-designs/msg564838/#msg564838
              and
Floor please delete messaage
https://overunity.com/19040/permanent-magnet-assisted-motor-coil-designs/msg564838/#msg564838

                                        Moving Attached files

1. Go to O.U.. com  / login
2. Start a reply in the "Floors dust bin"
3. Open a second browser and goto O.U..com  (you are already loged in)
4 Navigate to the Jpg. or png. or so on... that you want to copy, right click on
that file and select copy.
5.Switch to the other browser that is looking in the "Floors dust bin"
6. Below attach: click browse
7. Right click then select paste.
8. Change the name of the file you just pasted, else it has only a file type or extension.
                                  So ...  Right click on it then select rename.
9. left click on the renamed file to highlight it.
10. Left click on "open"

11. Post in your topic,  "Floor please delete messages x, y. z..."

             Again, the whole affair of moving a post, is a courtesy any way / for the record
             kind of thing and its is all your own call.
