Magnets, motion and measurement

[norman6538]

I am on version 6 and I made a variable lever with 3 different dowel diameters to be able to refine the power to set and reset the twist drive and this is what I measured today.
1. The device is self setting. ie meaning take my had off and it goes from unset to set and twist and lift a small washer 12.5 cm.
2.  then to unset and unlock from the twisted attraction it takes the same washer 2 cm of drop.
3. so that clearly gives 10 extra units of work for the switching necessary to make it self run.

The extra work out is more than enough.
Next I will begin my clock  work to make it switch from lifting to resetting mode making it a self runner with extra power out too.

Since my health is better and my wife has less nursing requirements from me

I'm glad for you of course, but ..
Good to you there ... I envy.  In our country no one will hear you.Nobody needs anyone but himself. Either indifferently will pass by, or say even die, I don't care.

Yes i would add to that, expressing one's hostility whenever getting a chance, that's sad.

@All readers

I posted this on another topic yesterday..
     But this is a slightly modified version   /  Typo corrected   /   re worded in a few spots



                                                              THE TWIST DRIVE

Twist Drive is the name I gave to a particular class of devices / magnet interactions, which embody specific sets of interactions between magnets. 

My own explorations of magnet interaction first began with a question.  It seems easier to separate two attracted magnets from each another by twisting them apart, rather than by pulling them directly away from each other.  Does it actually require less work to separate the magnets by twisting or is it that there is a kind of magnetic equivalent to leverage, which makes the separating easier, even though technically speaking, the amount of work done is the same either way ?  Pursuit of the answer to that question was a door way into a 7 years long exploration of magnets, their interactions and physics. 

I built my first two test benches, just to examine the differences between sliding, twisting and directly pulling magnets from each other.  The separation by twisting version I called the "twist drive".

I first considered the phrase "Torque Drive", which would have been a name with more sex appeal.  I chose instead, to christen it with the some what dorky "Twist Drive".  This was specifically to turn off and / or discourage attention from specific types of viewers / readers.  I'm not trying to create or promote a fad and  my videos and internet time are not monetized.  It is interesting to note, an individual (unknown to me) produced a YouTube video with a diagram of the device, wherein that presenter termed the device as the "Torque Drive".  I'm guessing that presenter expected more views and attention from the sexier name.  Yet another presenter of the "Twist Drive" chose to refer to it as "floor's magnetic torque amplifier".  Note however this presenter chose to present his own and other variations of / on the device, while never actually presenting a replication of the Twist Drive itself.

As an aside.
During the course of these explorations, I arrived at something of an understanding of the Bloch wall model.  The Bloch wall is a molecular structure found in permanent magnets, which provides a kind of magnetic shielding between the magnetic domains within those magnets.  That shielding is not an over unity event in itself, but it does represent / is a form of  magnetic shielding, known to exist in nature.

Now returning to the Twist Drive as topic.
Until recently, I had not fully understood, nor did I have a very complete explanation of, or theory of  why the twist drive interactions could result in over unity.  I was very much so misinformed as to just how substantial the difference between the attracting force and repelling force available between a given two magnets can be under certain conditions.

Be all that as it may and in contrast to its simple appearance, the Twist Drive itself, embodies a complex and extremely difficult to understand set of magnet interactions.  In some specific configurations, the twist drive demonstrates magnet interactions (energy exchanges) which result in a NET energy gain of ZERO (possible using springs).  This is the common view of magnet interactions, and one which is held by scientific convention as the only possibility.  In other specific configurations, the Twist Drive demonstrates dramatic    UNDER UNITY    results, wherein, convention holds that this simply cannot be.  Under unity is just as anomalous as is over unity (if there is no explanation as to where the energy goes).  To my mind, under unity and over unity are equivalent in value as proof of over unity, in that, the one reveals the path to the other.  Other configurations demonstrate  OVER UNITY  (more mechanical work out than is input).


                                                       THE TWIST DRIVE

I have insisted that in order that the reader can know whether the device works as claimed, she or he should see for their self.  Also ... tunnel vision by an experimenter is generally the rule, rather than the exception.  Peer review is essential to the scientific process.  If the claims are exceptional, then exceptional proofs are also needed.  Not only this, but faking results is too easily done in a video format.  Believers only clog up the process.  But please also understand that I DO consider beliefs of a certain order to be of value in one's life, over all.
...
The Twist Drive is not a device which utilizes the kind of magnetic force redirection (magnetic force shielding) which most readers of the "Magnets Motion and Measurement" topic may be familiar with.  It is a "different kind of animal".  Its over unity functioning is dependent upon the fact that the attraction possible between a given two magnets, is typically greater than the repulsion possible between those same two magnets.
...
The shapes of magnets, have major effects upon the how they interact with one another.  The magnets / magnet shapes which I have been using (3/8 by 7/8 by 1 7/8 inch ceramic wafer magnets, poles on the broad faces), give specifically these results.   Edge to edge.
...
Magnetic forces, whether attracting or repelling ones, increase when the distance between a given two magnets is decreased.  Those changes in force magnitude to distance are not linear.

                                Note that RO stands for rotating while SL stands for sliding.

In regard to the forces which motivate the SLIDING of  the SL.........
                                   
In an attraction mode, the rate of change in force magnitude to the change in distance (specifically at VERY near) is nearly linear, (nearly vertical  / over a very small distance) and the rate APPROACHES an inverse square relationship as the magnets get nearer to one another ( from very near until touching).

In a repelling mode, the rate of change in force magnitude to change in distance (specifically at VERY near) is nearly linear, (nearly horizontal over a very small distance) and the rate APPROACHES an inverse square relationship as the magnets get nearer to one another (until touching).

In attraction or repelling mode,  the rate of change in force magnitude to change in distance (specifically at far distances) become nearly linear (nearly horizontal) , and the rate APPROACHES an inverse square relationship.
...
The attraction possible between a given two magnets, is almost always greater than the repulsion possible between those same two magnets.

The DIFFERENCE in the force magnitude between when in an attraction mode and when in a repulsion mode, of a given two magnet, at a given same distance, is greatest when the magnets, are at either a near or very near distance.

The differences in force available during attraction modes and repulsion modes are due to changes in the magnetic polar orientations, of the magnetic domain structures within the magnets  (molecular and atomic domain structures).

                                                       THE TWIST DRIVE

When in repulsion, a given two magnets tend to weaken (demagnetize) each other.  When in attraction the same two magnets tend to strengthen (magnetize) each other.

There is a threshold in coercive magnetic force magnitude which must be reached, before domain reorientation become a major factor.   That force threshold is reached when the ceramic magnets I use, are in near proximity to one another.  The use of differing magnet materials, and the proportion of the strengths of the magnets used (in relationship to each other) will affect the magnet proximity
at which domain reorientations figure prominently.

There are other major factors, such as magnet shape which I do not considered here.
...
                                Note that RO stands for rotating while SL stands for sliding.

In regard to the forces which motivate the ROTATION of  the RO.........

During the rotation of the RO magnet in relationship to the SL magnet, by the magnetic forces, 2 attraction forces and 2 repulsion forces are present and CONTRIBUTING TO the rotation, always. 
................................................
When the RO magnet is crossed at its middle by the SL magnet at 90 degrees ......

As the section of the RO magnet which is ABOVE SL rotates from 90 degrees off from parallel to
SL, toward parallel to SL, the balance between the attracting and repelling forces shifts. 

Simultaneously, as RO rotates, the balances in forces between the section of the RO magnet which is
BELOW SL also shift. 
................................................
Above SL, and during ONE direction of rotation over a 180 degree course from parallel to again parallel.... attraction increases as repulsion decreases, while below SL, attraction decreases as repulsion increases as. 

Above SL, and during the OPPOSITE direction of rotation over a 180 degree course from parallel to again parallel... attraction decreases as repulsion increases, while below SL,  attraction increases as repulsion decreases.

These interactions are very complex, and words alone become utterly insufficient to describe them.  Watch the videos first or you will likely never grasp it. 
................................................
During the course of the RO rotation there are attracting forces (N/S and S/N) which contribute to the RO rotation.  N/S magnet pole orientations support N/S/N/S domain orientations.  N/S/N/S domain orientation are there by increased.  This in turn STRENGTHENS the attracting element's contribution to the rotational forces. 

Simultaneously there are repelling forces (N/N and S/S) which contribute to the RO rotation.  N/N and S/S magnet orientations tend to reduce N/S/N/S domain polar orientations.  This in turn WEAKENS the repulsive element's contribution to the rotation of RO. 


                                                       THE TWIST DRIVE

Up to the point at which RO is parallel to SL,  ONLY SOME of the forces act to increase / maintain N/S/N/S domain orientations.  Other forces (although still contributing to the rotation of RO) act to reduce N/S/N/S domain orientations.

When the SL magnet is aligned parallel to the  RO magnet (the rotation is completed), and the magnets are in attraction as both a  N to S alignment and a S to N alignment.  Now there are ONLY attractions and ALL OF THE FORCES act to, increase / maintain N/S/N/S domain orientations.  Forces are optimized  in terms of  causing the attraction of  magnet SL to magnet RO (straight line in a plane 90 degrees to the plane of RO rotation).

Finally, when the RO to SL, parallel alignment, results in a N to N and a S to S alignment  (both poles repelling),  the FORCE OF REPULSION is considerably weaker over the course of  the SL magnets travel (straight line),      than would be     the FORCE OF ATTRACTION present over the course of the SL magnets travel (straight line), if the RO to SL parallel alignment,  was instead N to S and S to N (both poles attracting).

Addemdum   


1. The sliding magnet (SL) is far from the Rotating magnet (RO).  RO is at a right angle to SL
    RO is practically free to rotate (because it is distant from SL)

2. RO is rotated 90 degrees against the very tiny magnetic forces.  (either a clock wise or counter clock wise direction,                (WORK IN)
depending upon magnet polar orientations).  What matter is that SL is now far from RO, but also parallel to and in ATTRACTION
to RO (SL barely wants to slide toward RO).

3. SL is pulled by attraction toward RO, almost touches RO.                                                                                                MAJOR  (WORKOUT)

4. RO is rotated back to 90 degrees off from SL against magnetic forces to  position # 1 again                                         MAJOR  (WORK IN).

5. SL is pulled to far from RO while SL is at 90 degrees off from RO.  This is against small attracting forces which are due to domain re-orientations.   (WORK IN)
