What magnetism tests have been done?

yeah the catch 22 of all this is every magnet is different. I dont have a magnetic viewer. But I would be curious to see a single cylinder field next to the same size cylinder comprised of smaller magnets, especially the lines it makes from end to center mass. But with every magnet being different, you solid magnet could be charged with 1.2 lbs of pulling force and the individual smaller ones might not have the same force . its something hard to prove given the randomness of the magnets creation. This is why I m doing weight tests.

the difference comes from the fact a single magnet is one piece everything about the magnet on the molecular level gives it its properties. Iron does not have a field untill you touch it to a magnet. then it becomes apart of the magnet. it gets its field impressed onto it. I dont think stacked magnets are that representation. They do not impress their fields on one other. They divert and contort the field. but in the end they are 2 fields stuck by attraction and the ends not touching have field diverted and contorted to them . Part of the field must be sapped to maintain the attraction. So the overall field should be getting smaller, with the end being boosted diminishing as more field is used to hold more magnets together. If my tests show a diminishing weight, Im still not certain if  it is proof of my theory as to why it happens.

I cant really see anything in your pictures :X

After rereading what You and I have posted(Dex), I wanted to take a minute to re- explain the course I am going down. I never recognized your comment on the reduction of force from center mass of the magnet. I didnt mean to ignore that fact, it does play a part. But as I stated, a stack of magnets has to use energy from its field to stay together, otherwise they "should" fall apart. So in effect distance plus sapping field to maintain a stack will lead to a very strong end, as well as the minimal force to break the stack. You are in the ball park area of my thinking. If a stack of magnets has such a large force to pull, and very little force required to break it in half, could one not pull with the full force of the large stack. Now the only way to break that force is to use some of the momentum gained to break the center of the large stack. This would occur as the moving magnet approaches the sticky spot. I imagine some kind of hinged sleeve on the stack, Now force used to break the stack is now less because with a hinge we are using leverage. So now we have distance, overall field sapping, and leverage which should reduce the amount of energy to break the stack quite nicely. Once the stack is broken , the new lesser pull is decelerating the moving object much less than the original full strength pull used to accelerate. In a nutshell trying to conserve momentum. So imagine a track that is the initial velocity, and these large hinged magnets that attempt to boost acceleration as well as an attempt to conserve momentum at the same time. I hope I explained this well enough. I did not just want to go all willy nilly buying stuff and trying to make it happen. With the shear amount of magnets, I figured it was best to gather some data.

I believe i stated a way I want to try and manipulate magnetic fields and the numerical effects shown in weight or a force. That is a magnetism test.

@ microcontroller: If you actually read the posts, mass and weight are being used to test the maximum field strength of magnets in certain physical positions. Unless you know of some secret mystical way to test the strength of a magnetic field, there isnt another way. It is true a magnetic field technically is not apart of the magnet. but the field would not exist without the sub-atomic and the atomic structure of the magnet that created the field.  How do you get magnetism without a mass or a magnet?  My tests using weight( mass and gravity as a constant) are to find the limitations of the magnetic field.  I am a layman, and knit picking over a definition label, will really get you know where with me. Your 2 posts have brought nothing fruitful like Dex's posts have.
