"Magnet shear to direct pull work ratio"
« on: July 16, 2020, 02:59:39 PM »
This topic is for presentations of
             the methods of measuring
                             and
            the measurements taken of

the work needed to shear two permanent magnets in attraction from one another
               as compared to
the work needed to pull those same two magnet directly apart from one another.

@ All readers

I'm setting up for measurements.  It will probably be a number of days
before I have any thing to show.

I will be using wafer / ceramic magnets cut down from 1 7/8 inches
length to 7/8 of an inch length.

3/8 thickness by 7/8 by 7/8 (square face) wafer magnets. 
Magnetic poles are on the broad faces.

Please see the attached Jpg drawing below.

I will measure a few variations in the magnet position
by the time I am done.

Suggestions are welcomed.

Here is someone else's Old project.  ( pdf file format )

    EDIT          The " Kedron_EDEN_Project.PDF  " attached below

I don't at this point, say their "findings" are either valid or not valid.

I cut up two magnets yesterday (out doors).

You can have my magnets when you pry them from my cold wet hands !

Not the smoothest / best quality of cuts, but they should do well enough.

See picture below.

First measurement set, no calculations.

7/8 x 7/8 inch by 3/8 inch thick.
Magnetic poles are on the broad faces.
The polar faces of the two magnets, begin as facing and aligned one over the other.
There is a 3 /32 inch gap between the two polar faces of the magnets.
The magnets are slid apart by adding force in10 gram increments.

Each degree is equal to 0.27930 of a mm travel on the sliding magnet.

Finished it out any way.

No calculations done.

Interaction as in above jpg

Magnetic poles are on the broad faces.
The polar faces of the two magnets, begin as facing and aligned one in front of the other.
There is a 3 /32 inch gap between the two polar faces of the magnets.

The magnets are pulled directly apart by adding force in 15 to 20 gram increments.

107 degrees worth of travel    and     95 degrees worth of travel...

100 / 107 = 0.9345794392523364485981308411215
0.9345794392523364485981308411215 x 95 = 88.785046728971962616822429906542

95 degrees of travel  is
             88.8 % of the travel of 107 degrees of travel .... .... .... .... ....

100 / 11293 = 0.00885504294695829274771982644116

0.00885504294695829274771982644116  x  9998 = 88.53

                                            9998 is 88.53 % of 11293 .... .... .... .... ....

No O.U. in this layout, doesn't prove that different magnet dimensions
or using neodymium magnets would not come out to O.U..   

But it doesn't look good to me, at this point.

Again...
     there are two more actions to measure.

                         This process is not complete.

Note I had previously diagrammed the input and output, backward.

But the work totals / measurements will still tell the differences, either way.

                       THIS DIAGRAM (BELOW) AGAIN, SHOWS THE ACTION BACKWARD
