What magnetism tests have been done?

[Fester]

Yes my magnets are coated. Almost everyone uses them, so I should have said up front though. Secondly I would like to point out, my fluid ounces are US fl.oz. I dont think the old english imperial fl oz is used anymore, so I didnt see a reason to state as such.

There are advantages and disadvantages to doing measurements like these, with a liquid.

adjustability, adaptability, accuracy of measurement,

But, there are trade-offs for that, which can affect the accuracy of the results, cause inconvenient situations, ect. - which, im sure you have already experienced.

I guess the important question i have to pose here, is this...

if there are variances in forces due to the liquid being in motion, there are variances in your magnetic field, because of the arrangement of the coated magnets.....

  What exactly is the point in stacking them in a non-symmetrical fashion, i.e. 2 on one side, one on the other..   

         Are you really learning anything by attempting to do that in this particular manner?

1) There are solid mass measuring methods, that would get rid of the water problems
2) If you insist on using asymmetrically stacked coated magnets, you need to learn how to incorporate that into the magnetic equation. Otherwise, the best you can ever hope for, is to plot an exponentially curved line, by experimenting with varying field intensities. Which, i believe, was conquered thoroughly nearly 200 yrs ago.
-----------------------

Now, the other thing is, what exactly are you measuring?
    break-away force? from an accelerating field? (gravity)

Where is the time factor?
   there is no time, on the magnetic side of the equation, but when you translate that into the physical world, and gravitational fields, the  moment of inertia, and duration of subsequent acceleration have to be incorporated into the problem.

I see, how you want to draw some sort of similarities, by mass comparison, but what you are instead actually measuring, is a unique quality of those particular magnets.
This is their " holding" or "lifting" strength. in most cases (except when you stack them asymmetrically)
       This number is proportional to the Gauss of Tesla rating of the magnet, In industry you see this number rated in lifting lbs, or holding lbs
This ratio is not consistent from magnet to magnet, nor is there a unified scale to convert gauss or Tesla to lifting lbs, its ...... sort of like magnetic efficiency., some magnets are better lifters than others.

[Note: The above applies mainly to coupled pairs or sets of magnets,. not to be confused with another "lifting strength" value, which DOES display a consistent ratio between Gauss/Tesla and the ammount of paramagnetic material it will lift - paramagnetic induction.]

Yes water is a very poor measuring device, with the sloshing etc. And true no 2 magnets are alike, So any stack created would have to have its own force testing done. I wrote in my 5th post about what I was attempting to try and do. I may not have been to clear.

I want to take a stack of magnets. The more I stack, I get a stronger field on the ends. If Im not mistaken the field is the same size the the lines actually are condensed more to the ends.  Now the longer I make this stack, the weaker the center section gets. Much as dexor stated with some obviously well known equation. With that sack all connected, there is a very large force. now we  move object furthering its acceleration/ momentum by this very strong pull until gets just shy of the "sticky spot". An arm attached to the moving object could apply leverage at the outer most spot of the stack. This will take way some momentum outright. But breaking the weakest spot and using leverage( friction existing) would minimize it. This should result in a lesser drag effect than the pull we put in at the sticky spot. I am hoping this is not a zero sum effect. I am trying to do a conservation of momentum. Many tracks run with with excellent velocity, untill the end of the track. This would move the sticky spot for the track as a whole onto the stacked magnets. So stacked, it would be strong enough to pull off the end of the track, break the stack to a lesser force, and have to objects attraction to the start of the track be stronger than the remaining attraction of the broken stack.

It may be more beneficial to have a stack of magnets, and make the break away point 3 magnets in from the track. Its a stronger pull at that point, but would give increased leverage at the opposed end.

I hope this explains the path I want to go down.

ok , i think i understand where yur going with this...

To achieve yur goal, we're going to have to move yur understanding of the magnetic field to the next level. And by doing so, im going to have to upset the "time" assumption of Einstein's special theory of relativity........ Whis is ironic, because the very same equation, explains the interactions of the magnetic field lines, irrespective of time...

ok,.. when the field lines are close together, i.e. the center of the magnetic field,
acceleration is at a maximum, velocity of the magnetic energy-points is at a mininum (lenz), and the attraction force, (sqrt (distance)), is at a maximum - meaning th eentirety of the "field" is in the center where the field lines merge.

at the ends, where the field lines are separated to their maximum distance, acceleration is at a minimum, because, velocity is subsequently approaching the speed of light, and the magnetic energy-points are attracted back around to the center.

Magnetically speaking, the center is where the field intensity is at a maximum, the magnetic energy-points are slowed down because of attraction force.  repulsion and momentum of the combined energy-points keeps the entire field in constant motion. in the center they vortex around each other. So the effective "outside" field experienced is virtually 0. AT the center, the particle experiences a maximum acceleration force and begins its journey back up to close to light speeds. It is important to note, that while each invididual magnetic energy point can never travel at speeds greater than c , They exist in a complete loop, and therefore, propegation of the magnetic field occurs instantaneously, across an infinite distance. There is no speed restriction, and while intensity diminishes at the ^2 of the distance, a magnetic field propegates throughout the entire universe instantly. A field here, can affect (to some minute degree) things in a linear path on the other side of the universe.


The external effects of the field, occur at the ends, because the field lines (paths the magnetic energy points follow) are separated north and south, at a distance.

The size and shape of the field is going to change your effective outside "0 point".
   This is a logical fallacy to label this the point of least magnetic resistance, because it is simultaneously the point of greatest field-line density... but the cup must be both half empty and half full....

The classical understanding of magnetic fields, basically pertains only to the effect of those fields on physical objects. Not to the field itself. So when you have multiple fields interacting, in a purely magnetic interface, you have to take into account, the entire field, not just the point of interaction.

bcause changes on one side of the field, affect the opposite side, as well as whats going on in the center.

So what is your conclusion based on this? Not going to say I 100% understand this .. yet.
